Pics for my Group help..

Well first youll have to go on the admin area or about us pages on your group.Somewhere there youll see a button called"manage members"there you can change various group settings.Switch how mebers and contributers can add pictures to"approve on vote"or whatever its called,and put it on one vote if you are the only admin.After someone adds a picture,it wont be accepted until you approve it in the group messages area on the home pages left side underneath the group name.
