Custom Headers

Hi, I want to create custom headers for each page like this one:

http://themeforest.net/item/fortuna-responsive-multipurpose-wordpress-theme/full_screen_preview/12496833

But from looking in the page editor I can’t see where it is added? I can see that there are rows with heading text in them but I don’t see where they have specified the image? I don’t need a slider just a static image.

Thanks
