Mike, hang in there, the photos will appear just as they always have in the past when the photos were not showing.
I have been using auctiva for about 2 years now and LOVE the service. During the listing special on ebay, I was able to list almost 70 auctions in about 4 hours time. I couldnt do that with the ebay listing software! To dump this service just because of a few hours of images not showing is not in my best interest.
