Hey Guys, I wrote a tutorial on the JS way of doing this. You could just drop some JS into where you need to edit. Here is an example of how to do it if you’re still stuck: http://scottgale.com/using-pinterest-with-fancybox/2012/08/15/
Are you thinking this one? http://wordpress.org/extend/plugins/lightbox-plus/
I could take a look. Link me to the one you like to use and I’ll see how to modify.
