I currently have photopost, and don't like the way it looks. I hope to move somewhere as well.
There are other scripts that I've seen / used
http://coppermine-gallery.net/
http://gallery.menalto.com/

dismas - are you able to upload a photo to your "on the trail" category, and have that same photo be listed in your personal member's gallery?
photoplog may be what I'm looking for...
