There is a solution that the admin team at Infinite Histories found. However, you have to play around with the css.

On MediaWiki:Wikia.css, simply put in:

/* Background image */ body { background: url("image url"); background-size: cover; }

For image url, just upload your desired image to your wiki, then click on the full resolution link. It'll take you to the image root url. Copy this url and paste it in place of image url (keep the quotation marks " " there though)

Hope this helps!
