Possible to add image description below title in lightbox?

Hi there…we’ve got the responsive lightbox plugin working great on our site (here’s a page using it: http://morningstarmarble.com/inventory/granite/). Curious how hard it would be to customize the plugin so that it calls the “description” for each image to appear below the title at the top of the lightbox. Not a critical feature for us, but would be great if it was possible. Any advice would be much appreciated.
