I ended up installing coppermine and works awesome. The technical support at their site sucks and are very rude people, but if you have no problems your good to go.
hehe I don't know about them now, right now I use photopost, but they had good support when I used it, just a bit slow. The only reason that I changed was because it still had bugs and some issues, and the template system was a pain, cause it didn't have a global template, I had to edit all templates to make it look like what I wanted. But yeah coppermine is way better anyways, good luck with the site.
