I just requested a demo account, and when you upload an image to the gallery, you get this error: (Sorry, couldn't post in bug reports):

IPB WARNING [2] mkdir(./uploads/1120244923): Permission denied (Line: 650 of /modules/gallery/lib/gallery_library.php)
IPB WARNING [2] move_uploaded_file(./uploads/1120244923/gallery_1_1_5119.gif): failed to open stream: No such file or directory (Line: 666 of /modules/gallery/lib/gallery_library.php)
IPB WARNING [2] move_uploaded_file(): Unable to move '/tmp/phpyBjFwI' to './uploads/1120244923/gallery_1_1_5119.gif' (Line: 666 of /modules/gallery/lib/gallery_library.php)

:devil:

It's a permission setting, not a bug really.
