I have been looking for a script or hack that rotates the vBulletin_logo on each visit or hit... or well actually I don't care as long as it changes once in a while without me having to do it manually. I have finally figured out templates and replacements enough to see where vBulletin_logo.gif <img> code is stored but I have no idea how to automate rotation.
Has anyone seen anything like this or know how to do it?
