Hi David,
This seems to be a listing “imported from eBay”. The listing was originally started with the old GarageSale 7.0.8beta. It includes the old non-compliant footer and the image URLs still use the “unsecure” http protocol.
Following the steps here might help:
Steps #3 and #5 are the most important ones for you listing. Also, before trying, download GarageSale 7.0.10b2.
However, it might be that the “repair” command can’t repair the old eBay image URLs included in your item description so it might be the better idea to re-do the item description:
Copy the whole text from the item description in Preview mode, switch to Editor mode, clear the item description field there and paste in the copied text. If you then switch back to Preview mode you can add new images and select a design as usual.
Regards, Kristian
