Board Thread:Support Requests - Designing Your Wiki/@comment-7920233-20131028072719

I've been trying to find ways to make a wiki look more proffesional, and while looking around at more used wikis, i saw that gta.wikia.com has a custom image behind their Wordmark and Naviagation bar. (the palm trees and sky scenery at the top)

gta.wikia.com/MediaWiki:Wiki-navigation doesnt seem to have anything about it so im assuming its something else.

If anyone could tell me how to add an image like that it would be appreciated. Thanks!
