I guess this is it:

Looks to be working.

Is the ://ajax.googleapis.com/ajax/libs/jquery/1.6/jquery.min.js in html_header necessary? It gives a validation error and seems to work without it.

And I see that it watermarks first large image but not additional images? Not a deal breaker.

Nice look and more interesting than the old stand-by Lightbox. (which I couldn't get sql patch to install 1.5 even directly in phpmyadmin)
