Still working with the superb AW@K support, but no success yet. I list only one photo with eBay and the rest in the description. I realize that many don't even click "see description", but with my 2000 items on eBay, it's a reasonable savings.
Mr. Withgott of AW2K said they found a bug in picture listing and directed me to the update Aw2kU1659s.exe, but that did not resolve my problem, though that update requested a reboot of my system.
Thank goodness I can still download auctions and ship! Listing new products is a more palatable crisis.
Will keep posting on this topic until solution arrives.
