1). i have to rename the zp-config.php to whatever.php so that i can access login setup.php successfully. why?

2). after i login, i've got
zenphoto setup

* Step 1: Edit the zp-config.php.example file and rename it to zp-config.php . You    can find the file in the "zen" directory.
* Step 2: Edit the .htaccess file in the root zenphoto folder if you have the mod_rewrite apache module, and want cruft-free URLs. Just change the one line indicated to make it work.
* Step 3: Change the permissions on the 'albums' and 'cache' folders to be writable by the server (chmod 777 cache) (not necessary on Windows servers)
* Step 4: Come back to this page (just reload it if you're ready) and click "Go!" 

i've done step 3. i don't know if i have the mod_rewrite apache module. what should i do next?

thanks

i'm not sure which folder to upload the zenphoto in. my wordpress is installed under / public_html / bruce /. and the zenphoto is installed under public_html /zenphoto

is that all right?
