I discovered a better way to do it. Look at my ebay item 5663220102. I have a different picture in the header and gallery than the description. The way to do this is pick the images you want to show up in your description. Pick anyone of the images for the header and gallery. Post your listing then revise your listing. Go to the "Revise Your Item: Pictures & Item Details" and replace the url's in "Picture Web address (Free)" and "Gallery picture Web address" with the pictures that you want. You can get the url's from the manage images section of auctiva and cut and paste them over to your listing.
