Members are notified when new photos are added.
Cluster is a simple easy to use app that is ideal for sharing photos with friends and family.
Easy to set up and quite user friendly. Good chance to share pics and comments with others in a private forum.
Finally a completely easy to use photo sharing app that lets you write about the pictures too. I've tried a bunch, this is the best and easiest. My families love it!
