I am also having problem with the photos that are being uploaded to eBay. I couldn't get any gallery photos to go up on quite a few items and then the inside photos weren't going up either. I tried to upload some photos today and got a message about an error with Auctiva uploading.
Hope it resolves soon. It appears to be acting a little wonky anyway. It is disheartening to think you've uploaded to eBay and see only a photo or two instead of all you uploaded. Please fix!
