"Error: Unable to create dir:" When loaded throuh PHPnuke

I recently installed Gallery 1.1 on my site with PHPnuke 7.8. When I load gallery as a stand-alone (http://www.talenscove.com/modules/gallery/) it seems to work fine. However, when loaded as a module (http://www.talenscove.com/modules.php?name=gallery) I get the following error:

Error: Unable to create dir:
Fatal error: Call to a member function on a non-object in /homepages/22/d164699960/htdocs/modules/gallery/classes/Album.php on line 54

Heres all the info on my server:
http://www.talenscove.com/modules/gallery/ (stand-alone)
http://www.talenscove.com/modules.php?name=gallery (embedded)
Gallery Version: 1.1
Apache version: 1.3.33
PHP Version: 4.4.2
Not sure what OS the server is running, but the site is hosted at 1&1 hosting (http://www.1and1.com)
http://www.talenscove.com/phpinfo.php

Heres the contents of the config file as well:
