I took a look at your listing and viewed the source. The reason why the images along the borders are not showing is that somehow the path to those images is slightly different then what they should be. The images that are missing are your "Background" images. If you were to go back to that custom template that you created and search for the term "backgound" you will see that the url for those images have an extra "../" in front of the image. This is what is causing those images to not appear. Removing these extra "../" from those background images and I also see that those images are mising the quotation marks around them so here is an example of what yours now looks like:
<TD width="100%" background=../http://ti2.auctiva.com/ti/minty_tp.gif>
This is what it should look like:
<TD width="100%" background="http://ti2.auctiva.com/ti/minty_tp.gif">
By doing this to all of the background image your problem should be fixed. You will then want to copy that html and go to eBay to revise the listing.
I am not sure why this happened to you but I am currently trying to reproduce the problem to see if it is something that the editor did so we can make the proper changes.
I hope this has been useful.
