UPDATE: Home Sharing photos for screen-savers appear even more limited than before. After a brief test it appears as if the pool of Home Sharing photos "Shared with Apple TV" is in the few hundreds, nowhere near the (fairly modest) 3,000 that I have in the album I've selected for Home Sharing to display on the Apple TV. This sucks. I'm wondering though if it's something on the Mac side which needs changing. Going to dig into where the Home Sharing photos are stored for streaming/beaming/syncing to the Apple TV. ------- Original Post: As AppleTV users with large photo libraries well know, you could select any photo album/folder/project for use with the screen saver, and it would randomly display ALL the images from that folder. With the AppleTV 2 and 3, likely because there was limited storage on-device, the AppleTV would only sync about 1,000 or so images for display on the screen saver. 1,000 images may sound like a lot, but when there's 5-10 new images onscreen every 10 seconds or so, you notice the limitation *very* quickly. Worse, they synced batch of 1,000 images would rarely re-sync (an easy, if partial, fix that never came), so you could often be staring at the same 1,000 images for weeks at a time, knowing that your selected album/folder had many, many more images that were never displayed. For me, it was reason enough to keep my AppleTV 1 around, just to play music while watching ALL our favourite family photos.
