The answer is OUCH! You'd have to use the ebay Revise listing to move the HTML code for the Scrolling Gallery from top to bottom of the description section for the active 60. There's no cost to do the code move, just PAIN.
BTW...my honest opinion of TOP vs. BOTTOM on the SG, is ALWAYS TOP. I absolutely want to grab my customers' attention to the fact I have a FULL STORE to browse and buy. For long descriptions and pics, a bidder/buyer might not drop to the bottom to see the SG. I know some think it's a distraction from the item being sold, but IMHO you've already got interest or they wouldn't be looking, LEVERAGE IT WITH THE SG PSEUDO-AD. Also, bidders/buyers that look are often interested in how-much they can get on single ships to save money. I'm always looking at what-else I can get from a seller for that advantage.
