background image, fixed at top of page other sections overlay image.

[Garrett4488]

Hello, 
I am wanting to add a different image for each page. this image will be fixed at the top of each page with a fade at the bottom so that when scrolling down the image moves up and essentially disapears back to the background color. this image is only a background image so i would like the sections to overlap the image. to further explain and show with an example please go to Veepee.fr for reference. each category displays a different image and is only fixed at the top.

Is this simple to do by creating a section on each page where you can just add the image or maybe a banner or slideshow image with css code to have other sections overlap?

  

I am using latest version of broadcast theme

Thanks for the help.
