Q: How to show laptop iPhotos as screen saver thru Apple TV (2nd Generation)

Hey Hood Canal!

I understand you’re wanting to use your iPhoto library as a screensaver on your Apple TV (2nd Gen). I know using your own photos as a screensaver on your Apple TV is awesome. I’ll be more than happy to help!

There is a great resource that shows how to set this up: iTunes 12 for Mac: Play items in your iTunes library using Apple TV (2nd generation or later)

Stream photos from your computer to Apple TV

Once Home Sharing is set up on your computer and on Apple TV, you can use iTunes to stream photos to your home theater system.

1. In iTunes, choose File > Home Sharing > Choose Photos to Share with Apple TV.

2. In the window that appears, select Share Photos From, and choose a source from the pop-up menu.

3. Do one of the following:

    
    
   •  

     Choose “All photos, albums, events, and faces.”

      
    
   •  

     Choose “Selected albums, events, and faces,” and select the items you want to stream.

      

4. Click Apply.

For more information, refer to the Apple TV Setup Guide.

This article says it’s for iTunes 12, but I have confirmed it also works with version 11 as well. Once you have set up iTunes to share your iPhoto library with your Apple TV go to your Apple TV and open the Settings > Screen Saver > Photos > Then Under the section titled “Computers” you should see your library there and can choose what albums to use for the screen saver. Once you choose the photos you should be all set.

Thanks for posting on the Apple Communities!

Cheers!
