Very nice addon. Easy to use. But some features are missing. Especially more option in permissions. Like Upload Limit per usergroup or access to specific albums by usergroup. But I am sure this will be added! So far four stars. After adding this features this will be sure a five star addon :)
The bug where once you open a picture in an album you can't open others, without reopening first and just scrolling through - really is a big deal. I would love to see a fix for this.
Same bug as Phases below reported, please fix this. Please somebody develop this resource further and i'll pay up to 10$, its that simple 6 great. The're is also a nice non-official responsible fix on github (google for them).
