Well
I have hundreds of pictures also, Fortunately I always use the Main picture using eBay hosting, but all the additionals are hosting in Auctiva. And I have all my pictures saved in my Hard drive, I will wait until tomorrow if I won't see any solution yet I'm going to start to upload all my pictures starting on the more expensive Items, I don't have too much itmes on Auction, but I have more of a hundred in my store
