Showing caption and description in lightbox

Hello folks!

I am using EWSEL Lightbox plugin on my WP 3.7 website.
Lightbox opens up properly and it shows image and title.

Now, after a lot of didding around, i couldnt find how to (beside the title), and image description and caption in the lightbox.
Does anybody have any advices?

I think that the plugin uses colorbox, and here is the main code of the plugin : http://jsfiddle.net/tB7ym/

Any advices? 🙁
