Q: Missing thumbnails in shared photostreams
On an iMac running latest Mavericks, this is the home of my photo library and this is where I create shared photostreams. When I go into those shared photostreams, most of the thumbnails are missing. Only the ones from after December 23 appear; that coincides with when I installed Yosemite and then reverted to Mavericks using a fresh Time Machine backup. I can double-click the empty box and get the image, and I can right-click and select "find in library" so it certainly knows what image is supposed to be there and actually has it.
None of the options in the repair menu (repair thumbnails, etc.) have had any effect whatsoever. The images all show on our devices so it seems the cloud part is OK; the problem appears to be just within the Mac.
I'm pretty sure I could just recreate them all but that is a PITA in several ways, both for me to figure out which ones they are and also for the subscribers to get a whole new version of the same album(s). Clearly this is broken somehow. Any idea how I can fix it?

Try the following:
Disable Photo Stream in the System/iCloud preference pane
and Photo Sharing in iPhoto's iCloud preference pane.
Reboot and reenable both respectively. See if that will jump start Photo Sharing and Shared Photo Streams..
