when i finish chmd and edit config don't get what this is:
.htaccess RewriteBase is /zenphoto [Does not match install folder]

Setup was not able to write to the file change RewriteBase match the install folder.
Either make the file writeable or set RewriteBase in your .htaccess file to /gallery.

Can someone please tell me how i can change to correct and use this script please.

You will have to either chmod the .htaccess file so setup can write to it or if that does not work you will have to edit it yourself to correct the rewrite base.

okey it works ty
