A new feature available in Apple’s iOS6 is shared photo streams. In order to be able to accept photo steams from friends and family, there are a few setting you need to make sure are enabled on your device.
Firstly you need to be signed into iCloud with your apple account. To do this Follow the steps below:
Tap on Settings
Scroll down and tap on iCloud.
If you have not signed into iCloud with your Apple account you will be asked to do this now. Otherwise scroll down and tap on photo stream.
The “My Photo Stream” will sync new photos you take with your other apple devices. The “Shared Photo Streams” will allow you to accept shared photo streams from your friends and family.
Then go into the photo’s app and tap on photo stream to accept or create a new photo stream.
