Hello moneyloaned -
we are not aware of any current issues with thumbnail images displaying within accounts and after taking a look at a few accounts the thumbnails appear to be displaying correctly.
If you are referring to the Optional eBay Gallery images on a listing that is active on eBay, please feel free to file a support case with the details of what you are experiencing as well as a few sample items where you have found an issue to be occurring and we'll be happy to take a look.
