How to open gallery items in lightbox or modal frame?

The problem is that gallery items contain not image fields, but file fields.
So, if I try to edit items display in view "Image Thumbnail Grid" I can choose options for files. But there is nothing like lightbox or any modal frame there which would allow me to open a modal frame with node (content + comments) form thumbnail.

Do you have any ideas through which modules I can try to make it?
