It's me again...I thought I had figured it out, but should have known better. I went to active auctions and marked it to "edit". That took me to eBay. I removed all images at the ebay site. Then went back to the active auction in Auctiva and added back the correct pictures. Now my Gallery picture is gone from the auction. The old pictures still show in the auction below, however (hoping this is just a delay in processing through the system).
If anyone can help me, I appreaciate it!!!! Thank you!!!!
