I installed zenPHOTO on my new site, and I could upload all my art, but I get an error trying to access any through the thumbnails. Here is an example.

If those differ on those that work and those that don't, you might get a clue. I encountered servers that either allow access via FTP or via a script like Zenphoto. But not both. That means you have to switch rights frequently.
Since I am on our paid support page in advance that I personally cannot really help with server configuration itself as I don't setup my own servers at all.
Zenphoto is aimed at users with shared hosting which is where I mostly isntall and use it. I never encountered such issues (except the rare weird server as above).
But glad you got it working again. Sorry, that I can't help more.
