how to get a gravity form in an image to show up in a popover?

Trying to make the form you see here-->>http://www.coxchevy.com/

I know they are using popover plugin and gravity forms. i have them both, I just can't seem to get the form inside the background image. I know this is a gravity forms question, i've bought 2 gravity forms courses, still can't figure it out. any help would be greatly appreciated.
