No longer able to upload photos?

I'm mystified... It's been many months since I uploaded anything, but I sold a few recently so I wanted to upload some additional shots.

Bt now I am getting error messages when I try to save images. It says to fix the items that are in red, but only the image itself is red-outlined.  There is no recognizable person in any of the three shots I just tried to upload. (So far as I understand, they do not require releases and could be commercial rather than editorial.)  

How can I find out what is wrong?

And now it's working but I don't know why. That was weird.
