Hi,
Didn't see anything immediately obvious, but I might try a few tests. Only code that might be an issue is the Javascript, which may soon be disallowed. eBay is completely reformating the listing page and developing a coding standard. You'll know if you start getting API errors. Does that Javascript delete the eBay image (bottom) after 300 milliseconds?
That image moves to a new area at top of page with the new listing design.
