I have that sometimes with my photos, too. It often (not always) helps, when I go into the photo (edit) and change the display size, e. g. from 900 wide to 1024 or so. Then the photo is back. Mostly, but not as often as I wish, I then can even change it back to the old one and the photo still stay live.
