Change entire background of a 4.02

[Crank!]

How do I change the background of the entire install of a 4.02 version so that when I scroll down the image stays and does not move?

This image will cover the entire background not just the header but the whole site.

Thanks

I believe it's called doc_background in your Stylevars. You would add fixed to the CSS code.

colortype url(location/of/image/on/server.jpg) center center fixed

In you additional.css template, you can add background-size:cover to fill the whole page with your image, but this isn't supported in older versions of IE. You might want to settle on an image that's large enough to fill the screen when people browser with these super giant monitors they have these days, but optimized enough so as not to chew up resources.
