Version 1.3 adds permission settings for the Image Management tab.  You can now set user and group permissions on image folders that are inherited from one folder to the next in the same way that permissions are inherited for pages.  Not having this feature was a major oversight in earlier versions and it feels great to have it in the newest version.  Upgrade files for 1.2 -> 1.3 (and the much delayed 1.1 -> 1.2) will be coming soon, as well as tutorial pages to explain how to set permissions for image folders.
