Hi Thomas! I added the background using CSS, which I added to MediaWiki:Wikia.css on the wiki. Just replace the URL below with the URL of your image, and you should be good to go!

.MainpageHeaderWarhammer { background-image: url("http://images2.wikia.nocookie.net/warhammer40k/images/f/f0/Wiki_Header.png") !important; }
