Thanks for the responses --- sorry you're all having problems, too. I did read posts from earlier this week, but I thought the problems had been resolved.
The good news is: as of Sun. 10am EST, my photos are showing ... for now. The question is, will they be there this evening when the auctions are ending? And will I be able to upload the photos I need to use for new listings tonight? I guess I'll find out soon.
Good luck to all of us!
