After the members post a photo, they are having to log in again. They are logged in, post a photo, but then when it takes them back to the homepage of the gallery it says they need to login.
www.thescrapcity.com/gallery
If this happens to registered users it would be very helpfull if you posted a non-admin test user account, don't you agree?. In fact, you should do exactly as suggested in the docs, section "asking for support on upload issues".
Change URL of your coppermine gallery folder (no 'index.php' or similar at the end) to http://www.thescrapcity.com/gallery/
http://www.thescrapcity.com/gallery/ and
http://thescrapcity.com/gallery/
are not the same!
To avoid such problems you can use the following lines in your .htaccess file to force only the www version of your web site:
RewriteEngine on
RewriteCond %{HTTP_HOST} !^http://www.thescrapcity.com$
RewriteRule ^(.*)$ http://www.thescrapcity.com/$1 [R=301]
also, rename the gallery cookie so all cookies for http://thescrapcity.com/ go bad :)
