On Photos, Sounds, Videos there are extra boxes on the data entry screen.

The first one lets you select who can view the upload.

STANDARD

PROMOTIONAL

ELITE MEMBER

MODERATOR

You can highlight moew then one of them. So that only those people with that type of membership can view the upload. NOT SELECTING anything puts the upload into PUBLIC (non member veiw).

I would appreciate it if you have any adult uploads that you at least select STANDARD to please keep them out of the public domain. The website has a minimum adult age and standard requires membership. As they are already adults they can view adult uploads. 

NEXT BOX

type in a members name and they will be the only ones able to view the upload. NickNames Filter: You can use more then one name and select a group of people that can view the upload. Pretty simple.
