I hacked it to work by doing a search and replace of rel="Lightbox to rel="lytebox" in install/vbulletin-style.xml. Now it works for image even if they are embeded. I guess this sin't the best way to do things, but it works.

Now it would be great to have the option to add the images into lytebox groups so the slideshow feature works. All you need to do is get the plugin to ad rel="lytebox[$postid]" instead of rel="lytebox" and it would work.
