I have 100000+ photos on home server I want to use in Zenphoto, but it is only listing about 7000+ photos.
I tried this link:
http://www.zenphoto.org/news/help-my-images-aren-t-displaying-after-installation-and-setup-

1. i set all permissions to 777 for testing purposes
2. no safe mode enabled
3. not using mod_rewrite, .htaccess is in /zenphoto folder, but I dont know how it should look like
4. I'm trying this right now
   Some more stuff, I don't know if its important:
   I copied images via samba share, then set permissions via chmod
   "albums" folder in "zenphoto" folder is a symlink
   zenphoto finds all folders (i think) but not files in them

Since you did not tell anything about any errors, please first read:
http://www.zenphoto.org/news/why-are-some-of-my-thumbnails-sized-images-not-generated-why-does-zenphoto-make-my-server-crash-while-processing-images-
http://www.zenphoto.org/news/is-it-really-necessary-to-pre-cache-my-images-at-all-

Yeah, sorry I was not clear enough.
That's just it, I dont get any errors. On the frontend are some maps listed, most are not, and when I go to administration under "gallery stats" it says only some 7000+ images.
I tried accessing images directly and I got an 500 internal error, so I renamed .htaccess to .bak. Now I can access them directly and list directories via apaches default browser, and the number under gallery stats curiously went up a bit, some 100 photos...
Could reinstalling zenphoto be of any use?
