At the moment, image covers are available via CSS for specific wikis, for example the Monster Hunter wiki gives a logo as background to every user. Admins can even set the cover photo to be specific for different users!

To do this, visit Mediawiki:Wikia.css as an admin, then add the lines .UserProfileMasthead .masthead-info { background-image: url('URL'); } --replacing URL with the URL of the image you want. You'll have to adjust it appropriately if it isn't centered the way you want it, though.
