I have seen this when surfing around looking at other smf gallery pro sites and am wondering how they do it. It seems possible to make two columns pf catagories so you have two shorter catagories side by side rather than one long one. Its been a while since I've run across one of these sites but after searching through 23 pages of threads posted about gallery mods and hacks, I simply cannot find anything about it.
Hopefully someone here knows what I am talking about but if I run across one of these sites I'll come back with a link to show you. I had a few bookmarked for future ref but Firefox bit the dust and lost my bookmarks
