I believe if you go to ur gallery/classes/geeklog/User.php. Open it up and find this part in the file:
function loadByUserName($uname) {
global $_TABLES;
$result = DB_query("SELECT uid,fullname,email " .
"FROM {$_TABLES['users']} " .
"WHERE username = '$uname'");
$userInfo = DB_fetchArray($result);
$this->uid = $userInfo['uid'];
$this->username = $userInfo['username'];
$this->fullname = $userInfo['fullname'];
$this->email = $userInfo['email'];
$this->isAdmin = SEC_inGroup('Root', $uid);
$this->canCreateAlbums = 0;
change $this->canCreateAlbums = 0; to $this->canCreateAlbums = 1;
Save it and you should be good to go. But I am still using Gallery 1.4.1 but I have a test site for new builds and it still works....So good luck!
