A gallery displays several pictures in an array or similar layout.

Galleries can display images formed into rows and columns by use of the <gallery>...</gallery> parser (conversion of Wikitext to HTML) tag. Be aware that different screen size and browsers may affect accessibility for some readers.

Attributes and values[edit]

Attributes and values go after the word gallery and a blank space, and before the ending angle bracket: <gallery attributes...>

Green: ideal, Yellow: under half full, Red: orphan

Number of pictures on last row of gallery
with c columns (browser-dependent)
and p pictures (editor can control)

i.e. good number of pictures to have in a gallery:
1, 2, 3, 4, 6, 8, 12, 14, 18, 20, ...

Loading in images

When loading in images using the Insert > Images and media, you will get the following: [[File:Name of file|thumb|Caption]]

In a gallery, you must remove all brackets ("[" or "]") (Except in wikilinks that are embedded within captions). You must also remove the |thumb. Finally, remove the File: prefix. You will be left with the following: Name of file|Caption

This is acceptable to the gallery. If you do not want to include a caption, remove |Caption.

Syntax[edit]

There are several "modes" of galleries.

traditional:

"Traditional" mode is currently the default, and, as such, need not be specified. The basic syntax is: 

<gallery>
Detroit Publishing Co. - A Yeoman of the Guard (N.B. actually a Yeoman Warder), full restoration.jpg|1
Official_program_-_Woman_suffrage_procession_March_3,_1913_-_crop.jpg|2
Thurston, the famous magician - East Indian Rope Trick.jpg|3
Joseph Ferdinand Keppler - The Pirate Publisher - Puck Magazine - Restoration by Adam Cuerden.jpg|4
</gallery>

Which gives:

If you want to make sure that any future changes to the default gallery mode will keep this style of gallery, you may specify "mode=traditional", similar to the examples below.

nolines:

By specifying the "nolines" mode parameter, the boxes are removed. Using the same syntax as before, but replacing <gallery> with <gallery mode=nolines> we get:

packed:

Changing <gallery> to <gallery mode=packed> produces a centered gallery, with slightly to significantly less space around each image (depending on its relative width and height), as shown below. It may relatively enlarge some images that were smaller in the above views.

For lengthy captions under narrow images, it's probably best to add a heights= parameter to make the images somewhat larger, as the default small size, can lead to ugly images. See below.

Packed-overlay: This uses <gallery mode=packed-overlay> to produce captions overlaying the bottom of the image. The captions are probably best kept short.

Packed-hover:

This uses <gallery mode=packed-hover>. Hover your mouse over the images below.

Extended syntax

Besides mode, the extended syntax is (see gallery tag help and hereafter for full list of parameters): 

<gallery caption="Sample gallery" widths="180px" heights="120px">
Wiki.png|Captioned
Wiki.png|alt=The Wikipedia logo|Captioned with alt text
Wiki.png|[[Help:Contents/Links|Links]] can be put in captions.
Wiki.png|Full [[MediaWiki]]<br />[[syntax]] may now be used...
</gallery>

Which produces:

The widths= and perrow= parameters do nothing in the packed, packed-overlay, or packed-hover modes, and class="center" does nothing when perrow= is used.

However, the heights= parameter can be extremely useful in these modes. This parameter specifies the initial height to render every image thumbnail, before images are possibly scaled up (keeping their size ratio) by JavaScript to fill rows; when needed the Javascript will query the image server to get resized thumbnails for several scales between 100% (the initial height specified) and about 125%. This gives good-looking galleries that can fill pages even when their size ratio are not exactly the same and allows using the actual area available for displaying on narrow mobile and large notebook/desktop/TV, and printing on various paper formats. (This mode also allows horizontally auto-scrollable galleries by embedding them in a large container within a scrollable container sized to fit the page width).

For example, take the following: 

<gallery mode="packed">
Detroit Publishing Co. - A Yeoman of the Guard (N.B. actually a Yeoman Warder), full restoration.jpg|A Yeoman Warder, from a Victorian-era [[photochrom]]
Official_program_-_Woman_suffrage_procession_March_3,_1913_-_crop.jpg|The Official program of the 1913 Woman Suffrage Procession held in Washington, D.C.
Thurston, the famous magician - East Indian Rope Trick.jpg|[[Howard Thurston]] performing the [[Indian rope trick]]
Joseph Ferdinand Keppler - The Pirate Publisher - Puck Magazine - Restoration by Adam Cuerden.jpg|"The Pirate Publisher", a satire of copyright infringement from the magazine ''[[Puck (magazine)|Puck]]''.
</gallery>

gives:

As you can see, the narrowness of the image distorts the caption. This may easily be fixed by adding the heights= parameter, as such. 

<gallery mode=packed heights=200px>

Detroit Publishing Co. - A Yeoman of the Guard (N.B. actually a Yeoman Warder), full restoration.jpg|A Yeoman Warder, from a Victorian-era [[photochrom]]
Official_program_-_Woman_suffrage_procession_March_3,_1913_-_crop.jpg|The Official program of the 1913 Woman Suffrage Procession held in Washington, D.C.
Thurston, the famous magician - East Indian Rope Trick.jpg|[[Howard Thurston]] performing the [[Indian rope trick]]
Joseph Ferdinand Keppler - The Pirate Publisher - Puck Magazine - Restoration by Adam Cuerden.jpg|"The Pirate Publisher", a satire of copyright infringement from the magazine ''[[Puck (magazine)|Puck]]''.
</gallery>

gives:

Other advice for using packed mode is to keep captions for particularly narrow images as short as is convenient.

Captions

For all modes except traditional, captions are centered. To left-align the captions, specify the CSS declaration text-align:left in the style= attribute: 

<gallery mode=packed heights=150px style="text-align:left">
Detroit Publishing Co. - A Yeoman of the Guard (N.B. actually a Yeoman Warder), full restoration.jpg|A Yeoman Warder, from a Victorian-era [[photochrom]]
Official_program_-_Woman_suffrage_procession_March_3,_1913_-_crop.jpg|The Official program of the 1913 Woman Suffrage Procession held in Washington, D.C.
Joseph Ferdinand Keppler - The Pirate Publisher - Puck Magazine - Restoration by Adam Cuerden.jpg|"The Pirate Publisher", a satire of copyright infringement from the magazine ''[[Puck (magazine)|Puck]]''.
</gallery>

gives:

To center a caption when other options are ineffective, perhaps the most-reliable alternative is to use:

yourimage.jpg | <div style="text-align: center;">yourcaption</div>

Center[edit]

To center a gallery use class="center": 

<gallery class="center">
Detroit Publishing Co. - A Yeoman of the Guard (N.B. actually a Yeoman Warder), full restoration.jpg|1
Official_program_-_Woman_suffrage_procession_March_3,_1913_-_crop.jpg|2
Thurston, the famous magician - East Indian Rope Trick.jpg|3
Joseph Ferdinand Keppler - The Pirate Publisher - Puck Magazine - Restoration by Adam Cuerden.jpg|4
</gallery>

Which gives:

The use of the perrow attribute will cause this to not work. Where a specific number of images per row is desired, use separate <gallery> elements. Centered galleries are the default for most variant gallery modes.
