Editing Help:Images

This page explains the '''image''' syntax when editing the BattleTechWiki.

== Getting Started ==

* You should first read up on [[Policy:Images|our policy on the use of images]] 
* You or another user must usually [[Help:Managing files|upload an image]] before you can use it on a BTW page.
* Images that are stored on BTW are usually rendered by using the <code>File:</code> namespace prefix as the target of a MediaWiki link.
* The alternate <code>Media:</code> namespace prefix is also usable to reference the original media file content (for rendering or downloading it separately, out of any page).

== Supported media types for images ==

The following file formats are supported by default:

* <code>.jpg</code> or <code>.jpeg</code> - bitmap image compressed in the standard JPEG format (this lossy format is most suitable for photographs).
* <code>.png</code> - bitmap image in the ''[[w:Portable Network Graphics|Portable Network Graphics]]'' format (specified by the ''W3 Consortium'').
* <code>.gif</code> - bitmap image in the legacy ''Graphics Interchange Format''.
* <code>.webp</code> - [[w:WebP|WebP]] supports both lossy and lossless compression while reducing image size by up to 45%.

Other formats used on the BattleTechWiki are:

* <code>.svg</code> or <code>.svgx<//code> - scalable image in the ''Scalable Vector Graphics'' format (specified by the ''W3 Consortium'').
<!-- * <code>.tiff</code> - Tagged image format. Often used for high-resolution archival photographs. Often used with {{ll|Extension:PagedTiffHandler}}.
* <code>.ogg</code>, <code>.oga</code>, <code>.ogv</code> - Ogg multimedia (audio or video). Not an image format, but treated similarly. Often used with {{ll|Extension:TimedMediaHandler}}
* <code>.pdf</code> - multipaged documents in the ''Portable Document Format'' (initially specified by ''Adobe''). Often used in conjunction with {{ll|Extension:PdfHandler}}
Other media types may be supported, but it may not be possible to display them inline.
-->

== Rendering a single image ==

=== Syntax ===

The full syntax for displaying an image is:
 <nowiki>[[</nowiki>File:''filename.extension''|''options''|''caption'']]

where ''options'' can be empty or containing one or more of the following lower-case words, separated by pipes ('''|'''):

* ''[[#Format|Format]]'' option: '''border''', and one of '''frameless''', '''frame''' (or '''framed'''), or '''thumb''' (or '''thumbnail'''). Note: '''border''' can be used in combination with '''frameless''' but will be ignored if used with one of the other options.
*: Controls how the rendered image is formatted and embedded in the rest of the page.
* ''[[#Size and frame|Resizing]]'' option: one of
** ''{width}'''''px''' — Resizes the image to fit within the given maximum width in pixels, without restricting its height. (Only whole-number pixel values are supported. A space character between the width value and "px" is permitted.)
** '''x'''''{height}'''''px''' — Resizes the image to fit within the given maximum height in pixels, without restricting its width. Only whole-number pixel values are supported. A space character between the height value and "px" is permitted.
** ''{width}'''''x'''''{height}'''''px''' — Resizes the image to fit within the given width and height in pixels. Only whole-number pixel values are supported. A space character between the width value and "px" is permitted.
** '''upright''' — Resizes an image to a multiple of the user's thumbnail size preferences – or the default thumbnail size, for logged-out users or logged-in users who have not changed their preferences – to fit within reasonable dimensions. This option is often useful for images whose height is larger than their width. Requires either '''thumb''' or '''frameless'''. Setting <code>|upright=1.0|</code> will display the image at the user's default image width. <code>|upright=2.0|</code> will display the image at double the user's default width.

* ''[[#Horizontal alignment|Horizontal alignment]]'' option: one of '''left''', '''right''', '''center''', '''none'''. If multiple of these options are present, only the first one will be used
*: Controls the horizontal alignment (and inline/block or floating styles) of the image within a text (no default value).
* ''[[#Vertical alignment|Vertical alignment]] option'': one of '''baseline''', '''sub''', '''super''', '''top''', '''text-top''', '''middle''', '''bottom''', '''text-bottom'''
*: Controls the vertical alignment of a non-floating inline image with the text before or after the image, and in the same block (the default vertical alignment is '''middle''').
* ''[[#Altering the default link target|Link]] option'': one of
** '''link='''''{target}'' — Allows to change the target (to an arbitrary page title, or URL) of the generated link, activable on the rendered image surface; e.g. <code><nowiki>[[File:Example.jpg|20px|link=http://www.wikipedia.org]]</nowiki></code> renders as [[File:Example.jpg|20px|link=http://www.wikipedia.org]] (external link), or <code><nowiki>[[File:Example.jpg|20px|link=MediaWiki]]</nowiki></code> renders as [[File:Example.jpg|20px|link=MediaWiki]] (internal link).
** '''link=''' (with an empty value) —  Displays an image without any activable link; e.g. <code><nowiki>[[</nowiki>File:Example.jpg|20px|link=]]</code> renders as [[File:Example.jpg|20px|link=]].

* Other specific options:
** '''alt='''''{alternative text}'' — Defines the alternative text (maps to the HTML attribute <code>alt="..."</code> of the generated {{tag|img|single}} element) of an image that will be rendered if either the referenced image cannot be downloaded and embedded, or if the support media must use the alternative description text (e.g. when using a Braille reader or with accessibility options set by the user in its browser).
*:If there is a space character between <code>alt</code> and the equals sign, the alt statement will be treated as a caption.
** '''class='''''{html class}'' — Defines classes (maps to the HTML attribute <code>class="..."</code> of the generated {{tag|img|single}} element).
** '''lang='''''{language code}'' — For SVG files containing [http://www.w3.org/TR/SVG/struct.html#SwitchElement &lt;switch&gt;] statements varying on a ''systemLanguage'' attribute, selects what language to render the file in. The default is the page language (defaults to project default language on most projects).
<!-- 
** '''page='''''{number}'' — Renders the specified page number (currently only applicable when showing a .djvu or .pdf file). 
** '''thumbtime='''''{number}'' — Renders a thumbnail from the video at the specified timestamp in seconds or MM:SS or HH:MM:SS format (only applicable when showing a video file).
** '''start='''''{number}'' — When video playback is started it will start at the specified timestamp in seconds or MM:SS or HH:MM:SS format (only applicable when showing a video file).
** '''muted''' — When media playback is started, audio will be muted.
** '''loop''' — Media will loop continuously. (only applies to audio and video)
-->
====Notes====
* The ''Link'' option does '''not always''' work with the thumb, thumbnail or frame formats. (This works for external and internal links)
* The image will always retain its [[w:aspect ratio|aspect ratio]].
* Images in non-scalable media types can be reduced in size, but not increased; e.g., bitmap images cannot be scaled up.
* The <code>upright</code> setting does not require an equals sign, i.e. <code>|upright 2.0|</code> works the same as <code>|upright=2.0|</code>.
* When used without a value or an equals sign (e.g., <code>|upright|</code>), defaults to <code>|upright=0.75|</code> (although <code>|upright=|</code> is the same as <code>|upright=1.0|</code>)
* The default maximum size depends on the ''format'' and the internal image dimensions (according to its media type).
* If there is a space character between <code>link</code> and the equals sign, the link statement will be treated as a caption.
* Including some HTML character equivalents, like <code>%22</code> for <code>"</code>, can cause the link statement to be treated as a caption.
* If a parameter does not match any of the other possibilities, it is assumed to be the caption text.
* If more than one non-parameter string is present, the final non-parameter string will be used as the caption.
* Caption text shows below the image in '''thumb''' and '''frame''' formats, or as tooltip text in any other format.
* Caption text displayed in the '''thumb''' and '''frame''' formats may contain wiki links and other formatting.
* If 'alt' is not specified and a caption is provided, the alternative text will be created automatically from the caption, stripped of formatting, except when in ''thumb'' or ''frame'' mode since the caption is already readable by screen readers in that case.

=== Format ===
{{collapse top|title=The following table shows the effect of all available formats.}}
{|class="wikitable plainlinks"
|-
!Description
!You type
!You get
{{/frame|frame=|ex=no format specified|float=no|inline=yes|render caption=no}}
{{/frame|frame=border|ex='''border''' results in a very small gray border|float=no|inline=yes|render caption=no}}
{{/frame|frame=frameless|ex='''frameless''', like thumbnail, respect user preferences for image width, but without border and no right float|float=no|inline=yes|render caption=no}}
{{/frame|frame=frameless|2=border|ex='''frameless''' and '''border'''|float=no|inline=yes|render caption=no}}
{{/frame|frame=frame|ex='''frame'''|float=yes|inline=no|render caption=yes}}
{{/frame|frame=thumb|ex='''thumb''' or '''thumbnail'''|float=yes|inline=no|render caption=yes}}
|}
{{collapse bottom}}

==== Notes ====
* When the height of an image in thumbnail is bigger than its width (i.e. in portrait orientation rather than landscape) and you find it too large, you may try the option <code>upright=N</code>, where N is the image's aspect ratio (its width divided by its height, defaulting to 0.75).
* The alternative is to specify the desired maximum height (in pixels) explicitly.
* By writing <code>thumb={filename}</code>, you can use a different image for the thumbnail.
* In the examples above, the original size of the image is 400×267 pixels.

=== Size and frame ===
{{collapse top|title=Among different formats, the effect of the size parameter may be different, as shown by expanding this.}}
{|class="wikitable"
|-
! Format
! Reduced
! Enlarged
{{/size|frame=}}
{{/size|frame=border}}
{{/size|frame=frame}}
{{/size|frame=thumb}}
{{/size|frame=frameless}}
|}
{{collapse bottom}}
==== Notes ====
* For how it appears when its size is not specified, see [[#Format|Format]] section above.
* When the format is not specified, or only <code>border</code>ed, the size can be both reduced and enlarged to any specified size.
* In the examples above, the original size of the image is 400×267 pixels.
* An image with <code>frame</code> always '''ignores''' the size specification; the original image will be reduced if it exceeds the maximum size defined in user preferences, and the page information will display a Linter error.
* The size of an image with <code>thumb</code> or <code>frameless</code> can be reduced, but cannot be enlarged beyond the original size of the image.

=== Horizontal alignment ===
{{collapse top|title=The following table shows the effects of horizontal alignment.}}
{|class="wikitable"
|-
!Description
!You type
!You get
{{/frame|2=100px|frame=|ex='''no horizontal alignment specified''', or default alignment|inline=yes|float=no}}
{{/frame|2=100px|frame=none|ex=specify horizontal alignment as: '''none'''|inline=no|float=no}}
{{/frame|2=100px|frame=center|ex=specify horizontal alignment as: '''center'''|inline=no|float=no}}
{{/frame|2=100px|frame=left|ex=specify horizontal alignment as: '''left'''|inline=no|float=yes}}
{{/frame|2=100px|frame=right|ex=specify horizontal alignment as: '''right'''|inline=no|float=yes}}
|}
{{collapse bottom}}
==== Notes ====
* When using the <code>frame</code> or <code>thumb[nail]</code> formats, the default horizontal alignment will be ''right'' (As BTW's default and only language is English, and it is a ''left-to-right'' language.)

=== Vertical alignment ===
The vertical alignment options take effect only if the image '''is''' rendered as an inline element and '''is not''' floating.
They alter the way the inlined image will be vertically aligned with the text present in the same block before and/or after this image on the same rendered row.

==== Examples ====
In these examples, to show the alignment result more clearly, the text spans are overlined and underlined, the font-size is increased to 200%, and the paragraph block is outlined with a thin border; additionally images of different sizes are aligned:

====Notes====
* The rendered line of text where inline images are inserted (and the lines of text rendered after the current one) may be moved down (this will increase the line-height conditionally by additional line spacing, just as it may occur with spans of text with variable font sizes, or with superscripts and subscripts) to allow the image height to be fully displayed with this alignment constraint.
* The "middle" vertical alignment position of the image (which is also the default) usually refers to the middle between the x-height and the baseline of the text (on which the vertical middle of the image will be aligned, and on which usually the text may be overstroke), but not to the middle of the line-height of the font-height that refers to the space between the "text-top" and "text-bottom" positions ; the font-height excludes:
** The additional line separation spacing normally divided equally into two line-margins (here 0.5em, according to line-height set to 200%) above and below the font-height).
** The additional line spacing which may be added by superscripts and subscripts.
* If the image height causes its top or bottom position to go above or below the normal full line-height of text, the middle position will be adjusted after the increasing the top and/or bottom line-margins so that the image can fit and align properly, and all images (including those with smaller heights) will be vertically centered on the adjusted middle position (for computing the effective line-height, the text of each rendered row with the larger font-height will be considered).
* The "text-top" and "text-bottom" alignment positions also excludes the extra line spacing added by superscripts and subscripts, but not the additional line-spacing defined by the line-height.
* The "top" and "bottom" alignment positions take into account all these extra line spacings (including superscripts and subscripts, if they are present in a rendered line span). 
* When the image alignment constrains the image to grow above or below the normal line-spacing, and the image is not absolutely positioned, the image will cause the "top" and "bottom" positions to be adjusted (just like superscripts and subscripts), so the effective line-height between rendered lines of text will be higher.
* The "underline", "overline" and "overstrike" text-decoration positions should be somewhere within these two limits and ''may'' depend on the type and height of fonts used (the superscript and subscript styles may be taken into account in some browsers, but usually these styles are ignored and the position of these decorations may not be adjusted); so these decorations normally don't affect the vertical position of images, relatively to the text.

=== Stopping the text flow ===
On occasion it is desirable to stop text (or other inline non-floating images) from flowing around a floating image.
Depending on the web browser's screen resolution and such, text flow on the right side of an image may cause a section header (for instance, <nowiki>== My Header ==</nowiki>) to appear to the right of the image, instead of below it, as a user may expect.
The text flow can be stopped by placing '''<syntaxhighlight lang=html inline><br clear=all></syntaxhighlight>''' (or if you prefer, <syntaxhighlight lang=html inline><div style="clear: both"></div></syntaxhighlight>) before the text that should start below the floating image.
(This may also be done without an empty line by wrapping the section with the floating images with <syntaxhighlight lang=html inline><div style="overflow: hidden">…</div></syntaxhighlight>, which clears all floats inside the <code>div</code> element.)

All images rendered as blocks (including non-floating '''center'''ed images, '''left'''- or '''right'''-floating images, as well as '''framed''' or '''thumbnail'''ed floating images) are implicitly breaking the surrounding lines of text (terminating the current block of text before the image, and creating a new paragraph for the text after them).
They will then stack vertically along their left or right alignment margin (or along the center line between these margins for '''center'''ed images).

=== Altering the default link target ===
{{collapse top|title=The following table shows how to alter the link target (whose default is the image description page) or how to remove it.
Changing the link does not alter the format described in the previous sections.}}

== Rendering a gallery of images ==

=== Gallery syntax ===
It's easy to make a gallery of thumbnails with the {{tag|gallery|open}} tag.
The syntax is:

<syntaxhighlight lang=html>
<gallery>
File:file_name.ext|caption|alt=alt language
File:file_name.ext|caption|alt=alt language
{...}
</gallery>
</syntaxhighlight>

==== Basic example ====
{{collapse top|title=Toggle source code view}}
<syntaxhighlight lang="moin">
<gallery>
File:Example.jpg|Item 1
File:Example.jpg|a link to [[Help:Contents]]
File:Example.jpg
File:Example.jpg|alt=An example image. It has flowers
File:Example.jpg|''italic caption''
File:Example.jpg|Links to external website|link=https://example.com
File:Example.jpg|link=w:Main_Page|Internal link
Example.jpg|on page "{{PAGENAME}}"
</gallery>
</syntaxhighlight>
</div>
{{collapse bottom}}
<gallery>
File:Example.jpg|Item 1
File:Example.jpg|a link to [[Help:Contents]]
File:Example.jpg
File:Example.jpg|alt=An example image. It has flowers
File:Example.jpg|''italic caption''
File:Example.jpg|Links to external website|link=https://example.com
File:Example.jpg|link=w:Main_Page|Internal link
Example.jpg|on page "{{PAGENAME}}"
</gallery>

=== mode parameter ===
The <code>mode</code> parameter takes options as follows:

* <code>traditional</code> is the original gallery type used by MediaWiki.
* <code>nolines</code> is similar to <code>traditional</code>, but with no border lines.
* <code>packed</code> causes images to have the same height but different widths, with little space between the images. The rows in this [[w:Responsive web design|responsive]] mode organize themselves according to the width of the screen.
* <code>packed-overlay</code> shows the caption overlaid on the image, in a semi-transparent white box.
* <code>packed-hover</code> is similar to <code>packed-overlay</code>, but with the caption and box only showing up on hover.
* <code>slideshow</code> creates a slideshow of the images.

==== Examples ====
All examples use the same images and captions, only replacing <code>mode="mode"</code> with the stated code.

=== Optional gallery attributes ===

The gallery tag itself takes several additional parameters, specified as attribute name-value pairs:

<syntaxhighlight lang=html>
<gallery {parameters}>
{images}
</gallery>
</syntaxhighlight>

* <code>caption="{caption}"</code>: (caption text between double quotes for more than a word) sets a caption centered atop the gallery. Only plain text may be used in the caption; formatting, templates and the like will not work.
* <code>widths={width}px</code>: sets the (max) widths of the images; the [[Special:MyLanguage/Manual:$wgGalleryOptions|default value]] is 120px. (It has no effect if mode is set to one of the following: packed, packed-overlay, packed-hover, slideshow.) ''Note the plural: width'''s'''''.
* <code>heights={heights}px</code>: sets the (max) heights of the images; the default value is 120px. (It has no effect if mode is set to slideshow.)
* <code>perrow={integer}</code>: sets the number of images per row. (It has no effect if mode is set to one of the following: packed, packed-overlay, packed-hover, slideshow.) 0 means automatically adjust based on width of screen.
* <code>showfilename={anything}</code>: Show the filenames of the images in the individual captions for each image (1.17+).
* <code>mode={traditional|nolines|packed|packed-hover|packed-overlay|slideshow}</code>: See section above (1.22+; 1.28+ for "slideshow").
* <code>showthumbnails</code>: For "slideshow" mode only, display the strip with image thumbnails below the slideshow by default (1.29+).

=== Notes ===
* The widths and heights parameters are taken more as suggestions than strict values for packed (and related) modes. 
* Packed modes will adjust the width of images in order to make each row the same length.

== Row of images that will wrap to browser width ==
This is an odd one, here are 3 examples that can possibly work.

=== Notes ===
* One way that works for a row of images with varying widths is not to use "thumb" or "left" or "none".
* If "thumb" is not used (and thus no captions) a row of images will wrap to the browser width.
* If necessary, narrow the browser window to see the images wrap to the next row.
* To '''align the top edge of images''' add the vertical-align command.
* To wrap images of varying widths with captions, it is necessary to use div HTML for an unordered list. Along with <code>style="display: inline-block;"</code>. For more info and ideas see: [http://www.sitepoint.com/give-floats-the-flick-in-css-layouts Give Floats the Flick in CSS Layouts].
* Outside a gallery, or the div HTML, it is impossible to have individual captions for images in a row of images that will wrap to the browser width.
* Weird things will occur!
** You may need to try saving it and see, as previewing it only works so well.
** Nothing else using wikitext works correctly. 
** Images can (and will) either overlap stuff on the right, or force a horizontal scroll bar.
* Using a left float ("left") for some images, combined with "none" for some of the images, will not work consistently either, especially if there is also a right sidebar of images.
* At narrower browser or screen widths, an image out of the row may appear far down the page after the end of the right sidebar of images.

== Link behavior ==
By default an image links to its file description page.
The "link=" option modifies this behavior to link to another page or website, or to turn off the image's linking behavior.

=== Display image, link it to another page or website ===
Use "link=" option to link image to another page or website:

Clicking on the below image will take you to [[BattleTechWiki]]:

 <nowiki>[[</nowiki>File:MediaWiki-2020-icon.svg|50px|link=BattleTechWiki]]

[[File:MediaWiki-2020-icon.svg|50px|link=BattleTechWiki]]

Clicking on the below image will take you to ''example.com'':

 <nowiki>[[</nowiki>File:MediaWiki-2020-icon.svg|50px|link=http://example.com]]

[[File:MediaWiki-2020-icon.svg|50px|link=http://example.com]]

=== Display image, turn off link ===

Use "link=" option with no value assigned to turn link off entirely; the below image is not a link:

 <nowiki>[[</nowiki>File:MediaWiki-2020-icon.svg|50px|link=]]

[[File:MediaWiki-2020-icon.svg|50px|link=]]

=== Link to an image ===

Add <code>:</code> as a prefix to the link you need to create.

 <nowiki>[[:</nowiki>File:MediaWiki-2020-icon.svg]]
[[:File:MediaWiki-2020-icon.svg]]
 <nowiki>[[:</nowiki>File:MediaWiki-2020-icon.svg|Wiki]]
[[:File:MediaWiki-2020-icon.svg|Wiki]]

=== Directly linking to an image ===
The above examples link to the image's description page.
To directly link to an image, the pseudo-namespace <code>Media:</code> can be used on MediaWiki pages:

<syntaxhighlight lang="moin">
[[Media:MediaWiki-2020-icon.svg]]
</syntaxhighlight>
[[Media:MediaWiki-2020-icon.svg]]
