Picture Sharing-Thing 4

I am intrigued to see other libraries using photo sharing for their libraries. What interests me most is how these folks get permission to use pictures of the public in the photos as much as they do such as all the students you see in the pics from Alexandrian Public Library. Additionally, you can tell that not everyone is uploading the information as the pictures do not always get labeled in the same manner such as the Old Bridge Public Library where many titles are sometimes capitalized and others not.
