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?

I looked into web albums a while ago, though I wasn't looking for multi-user functionality, since it's just me. None of the open-source apps really struck me as the bees knees. I had a very strong dislike for the presentation on Gallery, though. I ended up doing my own album with emAlbum, but I had to do a bit of hacking at it to make it a bit more palatable (I'm still not totally thrilled with it, but momentum keeps me from changing it to something else). Looking at the features, though, emAlbum doesn't appear to have multi-user support.

The goal is to not install for each user, though.
