Does Coppermine support pbase / gallery 2.x style URLs?
Example:
http://www.blah.com/gallery/username/album1
http://www.blah.com/gallery/username/album2
http://www.blah.com/gallery/username/album3
etc ..
No, may be in future versions...
But coppermine has short URLs.
Example:
http://www.yoursite.com/cpg/displayimage.php?pos=-12
where 12 is the pid of the picture.
also search for threads with mod_rewrite on the forum - they will help if you run Apache as your webserver
