Apple’s Photostream feature is one of my favorites 🙂 I like to take a lot of pictures and share them with family and friends. Hence, why I love Photostream. It is not perfect. I wish you could tag people and the UI has some unique elements to it, but it is what we got.
Here is a quick video on how to start your own!
P.S. Yes you can upload videos to Photostream as long as they are less than 5 minutes.
P.P.S On iOS 7 you can have multiple contributors to a photostream.
