Photo Database Application
I haven't tried it myself, largely because (like far too many other people) I've been working on-and-off on a similar project of my own, but it looks like FotoBilder might be exactly what you need. Fairly strictly web-based, and requires mod_perl (unless I'm very much mistaken), but if you don't mind those constraints, it seems like it could work pretty well for you.
If God had meant us to fly, he would *never* have given us the railroads.
