Hi Starrynight,
There are two ways to remove this "Description" image, one is to create a custom template like I discussed earlier in this thread, or two you may wish to list your item, then at eBay you can revise your listing, go in and find the image that you do not wish to use and cut it out. I apologize for the inconvienence until we can find a satisfactory resolution these are the only solutions I can think of currently.
