I have just upgraded templates to 7.5.2 and used jQuery to make a nice carousel out of the gallery island on my homepage. Works well.
Looking forward to ubbthreads v8 with its new div/css based layout - will put some jQuery javascript loveliness and shadowbox lightbox popups in if needed once its released and maybe supply some of the customised code back to the community (probably on ubbdevelopers site though).
Carousel here (3rd column)...
