The developer has given this below for testing purposes only. IMO it works quite well (WP 3.2.1).
v1.7-RC3 is in the trunk.
you can download it from here: http://downloads.wordpress.org/plugin/file-gallery.zip
- Among other things, it fixes the checkboxes issue that appeared after WP3.2 (new jquery).
If you found any bugs, please post them here below or at the forum, with proper description how to reproduce.
