I want to set up a web gallery system that uses space in each user's web directory. Keeping a central database is ok but not necessarily preferred. I was looking at Gallery but it looks like per-user galleries will be a bit of hacking, and sort of hackish at that. I have a Unix platform, and can pick from modphp (3 or 4, prefer 4), modperl, or something else, and can use mysql or berkeley db (or flat files).

What are you using? What do you like/not like?
