The screen saver on the Apple TV is a great way to show off your favorite photos, but the traditional way of updating it via iTunes can be a little cumbersome for many, and as a result, the photos can get stale. If you find yourself frequently wanting to add new photos to your screensaver, you’ll probably find it far easier to make use of iCloud’s Photo Sharing feature.
Since the Apple TV screen saver can be set to any of your shared photo albums in iCloud, all you need to do is setup an album for your screen saver and then select it on the Apple TV under Settings, Screen Saver. Once selected, you can add photos to this album from any of your iOS devices or your Mac in the same way as for any other iCloud shared album, and they’ll automatically appear in the mix on your Apple TV. As an added bonus, you can even share the photo album with other family members and give them publishing rights to let them contribute to the screen saver as well.
