Ok, having looked at some of your listings the above is not the issue in this case. The problem is that your image links are totally messed up; in fact the imported code is totally screwed.
Do the imported listings look Ok
before you edit them, or are they messed up immediately on import?
Your best bet may be to open a support request (
http://uk.ebid.net/contact.php) and attach the file you are importing into Ninja Lister to the request. Admin can then examine it for anything that may be causing the problems exhibited on listing.
