I use Jomsocial 1.8.x files that allows admins in frontend to transfer a jomsocial image from useralbums direct to the appropriate Joomgallery category. admins are able to add/select a Title,Description and Categorie within a seperate form.
These files must now be upgraded to latest:
you must fix the following issues:
* Transfer not possible if Jomsocial Amazon S3 is enabled for Photos
* Thumbnail size for transfered photos should respect the default Joomgallery Thumb size
you get the latest 1.8 files with a pdf description how it works.
