Thanks for the quick reply. I am using a theme called “Sabuy” and it has fancybox integrated into it. The bummer thing is that with Instapress installed and activated, not only does fancybox not work with the instapress widget, but it also kills the fancybox functionality throughout the rest of the site. Deactivating instapress restores the fancybox effect throughout the site. This is too bad because instapress is the best instagram plugin!
