Facebook groups have a more collaborative environment than Facebook pages or profiles, allowing members to contribute equally even if they do not have admin privileges. This cooperative nature extends to photos; any member of a Facebook group can upload one or more pictures, and after an album is created, any group member can add to it. If the admin sets the privacy of the group to “Open,” anyone on Facebook can see the photos, but if she sets the privacy to “Secret” or “Closed,” only group members can see uploads. Tips Writer Bio
