We recently switched from vBulletin to Xenforo. Some of our forums on vBulletin had custom logos that would display. The logos really looked more like a banner, but they displayed at the top of each forum. There was a setting (IIRC, Title Image, but I could be wrong) in the Styles & Templates section of the vBulletin Admin Control Panel for each forum that controlled it. With that setting, you could put in either the server location or external website location of the logo that you wanted to display. Does Xenforo have anything like this available?
