This help page covers the instructions of creating a photo, or picture gallery.
How to create a picture gallery
Galleries are best used in situations where a lot of pictures need to be displayed. Galleries are like thumbnails boxed together in a table.
By default, galleries have a fluid width. Do not create galleries with a fixed width on any page outside your userspace.
Here is an example of a gallery:
<gallery> Flag of Sierra.svg|[[Kingdom of Sierra|Sierra]] Flag of Brazoria.svg|[[Brazoria]] Flag of the United Commonwealth.svg|[[United Commonwealth]] </gallery>
The basic template for a gallery is this:
<gallery> Image name.ext|Caption </gallery>
