Lets say I wanna build an gallery just for myself ... i mean, i got pretty limited bandwidht and can't allow google spider to cache my pages and images and i want to limit those pages just on registered users... but no one will be able to register xcept me who got already account.. so in fact no one will be able to spend my bandwith except me... is that possible? too bad there isn't an option to "disable picture viewing" in groups for anonymous users ...
If you want no one else to view the gallery, put it into offline mode. As long as you are logged in as admin, you can view the gallery.
You can also edit your robots file, and set up a htaccess file (Apache only) to restrict robots.
Google for htaccess robots
Is there a way to only allow registred users to view full size images ?
