I have noticed that from last update the first image (which goes on eBay serves) is resized as all others I include in description. If I had 2000x3000 pixel images, before last update GS did not resize the first one and buyers could see 2000x3000 from eBay image box. Now it is resized 1200x800 as all other images that goes on your server. I hope you could fix this, it is very important that at least first image is full dimension.
Hope you could help
