Make sure you put constants.php and sessions.php in the includes folder and global.php in the gallery root. And make sure these vars in sessions.php are set properly:

define('VBLICENCE_NUMBER', 'XXXXXXXX'); //REPLACE XXXXXXXX with your Licence Number, usually on top of your vB files

define('SESSION_NAME', 's'); // Default of vBulletin is "s".
define('COOKIE_PREFIX', 'bb'); //Default of vBulletin is "bb".
define('COOKIE_TIMEOUT','900'); //Set the same with your vB timeout, in second
define('ALBUM_FOLDER','/album/'); //Your Album Folder WITH trailing slash

I just tried it with the files and it works.
