Getting things rolling now thanks to the great people on this forum.
I need to change the name of the /zenphoto folder on a site.

Could someone please tell me which ZP files contain references to that folder? I don't want to risk breaking my setup now by making a stupid mistake when I do the renaming.

You only need to change .htaccess, and only if you're using mod_rewrite for clean URLs.

Thank you! On to the CSS mods...
