on my Main web page. my backgrounds transition every few seconds to a new background. example: www.the-mec.net is there any way i can make them do the same thing on the forums? so they match, so you dont really notice a difference when you go between the main site and the forums themselves?
It is not supported by default, but you can just do it the same way as you did it on your own page, just modify the script to work on a XenForo installation, shouldn't be too difficult if you have set it up yourself.
