As of this morning, all my books had pictures. Tonight there are one that are missing, but say see larger image.

Anyone know anything about this?

I just noticed all my books had pictures yesterday and now none of them do...  Wonder what happened?

yep. A lot of my covers missing also.

All the covers on my reminder page are missing and half are gone from my TBR list.  Strange though cause it looks like the covers are present on my bookshelf.  Wonder what's going on.

I don't know, but the site is funky all over the place, it's not just cover images that are missing. Pages get stuck loading or take forever, partially load and sit there, red X's all over the place. I'm guessing they are doing some major upgrades to some stuff in the coding and it's affecting all sorts of other things. I won't worry about anything missing for at least a couple days. This kind of thing just happens on web sites. When they get lots of funky mishaps and partials and such, you can bet there's a programmer with his  or her fingers in there somewhere :)
