well, you'd have to look on my PC!!

i haven't posted it anywhere.. but, simply put you would do the following:
1) get lightbox stuff added to your site (add the js, css and also change showflat.inc.php, .tpl)
2) go to content tools and add a thumb tag that takes the url to the image and marks it up with rel="lightbox" in the <a> tag
3) adapt lightbox to have a larger initial thumb size (optional)
*poof* done
