How do I Recover photos from Apple TV screensaver

I used home sharing to upload my personal photos to Apple Tv to use as a screensaver. My coomputer crashed and I lost all my photos but they are still appearing on my apple TV screen saver. How to I recover them. Is there an online folder that has them somewhere or can I pull them back from the Apple TV?
