You can change who's allowed to see your photos at anytime. There are four privacy settings that you can choose for each album: 1. Everyone: your friends and people on your networks can see photos in this album. Additionally, if you tag anyone in this album, the friends of the people you tag will be able to see the photos in which their friends are tagged regardless of which network they are on. 2. All my networks and all my friends: only the people on your networks and your friends will be allowed to see the photos in this album.
