I, i posted zenphoto and extract packaged to hosting server www.remotehost under zenphoto directory. After installation and setup I can upload image files that are stored on DB but i can't see thumbnail and images and when I click foe example to my album link "carmo" i obtain these error:
Folder /zenphoto/carmo/ doesn't contain page index
I can see that carmo directory, in server file system, is under /zenphoto/albums/carmo/ nor under /zenphoto/carmo/
I tried to modified .htaccess (RewriteBase entry) but nothing happened

Disable the cruft-free URL's (line 46 in zp-config.php).

If you want to use the nice URL's then make sure that your host has mod_rewrite on. Mine was off per default (servage.net) and I used to have the same problem as you are having.
