I have the same problem. I am new to Auctiva - and have listed twelve items.
The first item that I listed is the only item that appears in the 'Store Window' on my auctions. I don't see any items, any pictures - nothing. And all my items have pictures.
I am not mad, but I just hope there is a solution for this. I made a couple of my items 'featured' but that still doesn't do anything.
Thanks
