Lightbox To Display Only One Post

Hi,
I’m struggling with Lightbox.

I have a page that displays multiple posts in a loop. Within each post is a gallery of about 3-6 images. I am using Lightbox to enlarge the thumbnails when clicked. this works great but instead of just displaying the photos related to that post, it displays all the photos from every gallery on the page….

How can I limit lightbox to only cycle through the photos in the relative post?

Thanks!
