My installation seems to be working, I can create albums, upload images, change their order, but when it comes time to actually view the album, the images don't show. Firefox just shows a little grey box.
When I click "open link in new window", that doesn't work either. The URL is:
http://conservationfit.org/zp/index.php?album=Test-album&image=DSCF0608.jpg
This is under a WordPress installation at the top level, but I don't think that's an issue...
