Stretch a picture to fill up the whole background of a webpage?

[Elgin Clock]

Is there any code (preferably html) that would allow the background image of a webpage to fully take up the page no matter what resolution you view it at??

I have an image sized pretty good for the page size, but on some resolutions I see it is too small and it tiles the image.

Is there any way to stretch the image (larger or smaller) to the actual html page size?

I basically have a picture that is meant too look like a sheet of paper with an image at the bottom, and it tiles itself and starts the new "piece" of paper again.

I want this page to look like it was written on the piece of paper image and have it be contained within the page.

Any help would be greatly appreciated.

Thanks in advance.
