This may sound simplistic, but why not have your wife contact Ebay complaining
that they are using a photo of her without her permission.
Further she can inform them that the only one that does have the right to use it is
Lumen lab, and then prove it was used using this link here:
http://web.archive.org/web/20040521074352/...//lumenlab.com/which is a cached copy of your site from March 21, 2004 found on this site:
http://web.archive.org/web/*/http://www.lumenlab.com/Which is an archive of older websites.
Further more she can state that she retains ownership of the image, and his using
it without permissiion violates international copyright law. She can also inform them
that she still retains the original image, as well as others from that same shoot that
she can provide as proof.
The key here is that the model who owns the images needs to file the complaint
