Nothing synched to skydrive.
I tried to put some photos in favorites to just use that as a live tile - but the pinned favorites just stays on one pic. I went in and set it to shuffle pics, tried removing and resetting it, and still, one pic.
I tried the reboot after deleting, it is still rolling through pics that are no longer there.
What DID work, however, was I unpinned photos, rebooted, and then repinned photos. It is now no longer showing pics I deleted.
I suspect this is just a bug with WP8. I have reported it to MS, so I'll let you know if they respond.
