using lightbox with the_post_thumbnail

Hi,

I’m wondering if anyone has some tips or tutorials for using <?php the_post_thumbnail(''); ?> with the JQuery lightbox plugin: https://www.huddletogether.com/projects/lightbox2/

Normally I would have been calling a custom field and just adding the rel=”lightbox” in the template, not too sure how it works with the above thumbnail call.

Thanks.
