[Plugin: NextGEN Gallery] Edit caption/description in lightbox popup

I’m running nextgen gallery with lightbox, and I can’t for the life of me find the code that controls the popup window full-screen view of images. Is it under the nextgen plugin? Lightbox?

I’m trying to get the album title displayed along with the caption/description. (And eventually some more buttons for a shopping cart plugin.)

Any thoughts?

Thanks.
