Normally I would use Firefox's inspector tool to see the styling applied to the relevant HTML elements, or look for the image's name in the style editor (after right-clicking > View Background Image to see the file path), but in this case I couldn't locate it so I just looked for it in the wiki's CSS pages (in this case it was in MediaWiki:Common.css).

CSS rule: .my-awesome-background {background-image: url("full-image-url-here");}
 * 1) Upload your image to your wiki.
 * 2) Add the CSS rule below to your Special:CSS page. Simply change the image URL, and the class name if you like ("." means class and you can call it anything, e.g. ".my-awesome-background").
 * 3) Apply the class to HTML elements as shown above; also works in wikitext table cells.

Note that you could use a slightly different method if you wanted every header cell in a table to use that rule without having to specify the class on each. You would instead use this rule: table.my-awesome-background th {background-image: url("full-image-url-here");} And use the class at the start of the table rather than each header cell.
