well the idea is that the administrator will create the gallery then give specific permission to a user so that they can view the gallery .. if I check "view gallery" on public and registered, won't that mean that everyone will be able to view the gallery?
Sorry, misunderstood the question.
There does not appear to be a way to do that. Zoom Gallery used to be able to do this but it was a pain in many ways. ANyway that project is dead. JoomGallery might do it but I don't know.
I Chose RSG2 for the moment because it seems to run OK in native mode, but I am having difficulty with issues like this one where I want users to be able to manage and create their own galleries without a lot of nonsense.
My luck has been moderate.
