Thanks for this useful plugin.
I think it would be great to add the following features to the plugin, it would make complete:
1- The ability to move between pictures in the same album by using "Next" and "Previous" buttons.
2- The ability to add music, videos and pictures directly from the corresponding tab rather than using the "Upload" tab.
3- The ability to define a thumbnail for the album.
4- The ability to define permissions on the uploaded media/album.
