I am poping up an old concern from 2 months ago. When a user set a photo privacy as [public] within an album, the media cannot be public once the related album privacy is not [public] too. I was wondering if such mechanism was implemented in CB Gallery 4 - see below the answer from the previous topic
Will review adding checks for minimum allowed privacy options for media based off album privacy. This isn't a priority issue though so that won't be reviewed and possibly implemented for awhile.
