Pin It button not finding images on page

[cadfile]

The Pin it button isn't working. The images aren't being passed to the Pinterest.

Here is the link the pin it button is showing

http://pinterest.com/pin/create/button/?url=[MY URL]&media=

It is blank after "media". I don't use featured images so I would think it should be grabbing the first image but I am getting the no image error from Pinterest. The error happens on Firefox and Chrome but the separate Pin It browser buttons work fine.
