photo permission inheritance. We want to use the folder permissions unless specific permissions have been set to over-ride them. If nothing is set, use the channel default. We may have to mess with his further in the case of somebody trying to create a public photo directory when their normal permissions are set to private. Kind of a chicken/egg problem because the folder permissions will be empty.
