I miss the feature where you can define folders/subfolders where you want users to log in before they can view the pictures in that folder. I guess it's okay that the folder is present in the menu, but if someone tries to view it, the user will be asked for user credentials.
I can see the forum discussion with the topic 'Hidden folders', but the restricted user will not help in this case. Isn't that just for selecting where the user in question can upload pictures??
