I'm evaluating Zenphoto at zenporary.schmonz.com.

In 1.2 (and 1.2.1, which I'm now running), when I click any thumbnail expecting to get the corresponding full image, I get "The Zenphoto object you are requesting cannot be found". I'm pretty sure (but not completely sure) this used to work in 1.1.7. I'm very sure I'd like it to work now. ;-)

The only non-default settings I have in zp-config.php are mysql_user, mysql_pass, mysql_database, UTF-8 (true), and album_folder ('/home/schmonz/sites/zenporary.schmonz.com/albums/') and album_folder_class ('external'). The problem must have to do with those last two.

(While fiddling with those settings, my 1.2.1 upgrade lost its album titles and apparently other metadata. There was an error about the syntax of an SQL query just beforehand, but I didn't keep any of that around, and for now I'm not worried about it unless it could somehow be related to the primary problem.)

What am I doing wrong?

This is supposed to work, right? I'm not opposed to doing a clean reinstall -- I only have a few small albums, and haven't added any important metadata -- but I'm curious if I'm misunderstanding something fundamental, first.
