Hi guys, i'm searching for a mod or hack that changes the logo of the website, or the header on differents forums, like:

Forum 1 -> Logo1
Forum 2 -> Logo2

Thanks u very much

Yup! me 2, many templates use the logo.gif but it only 250x112 , not as long as the length of the header, i can't find logo.gif in the templates search, where can i find it and how can i edit it to put my logo fitting the header?
thank you!
