I know there is a tutorial for this, but I don't know what to call it to actually track it down.

I have an image that I want to stretch across the width of the page 100%. It will be used as a divider between subject matter. Can you direct me to a tutorial or info on how to do this.

Here is a link to the image so you can see what I currently have:


Instead of creating an image 1000 px wide, I want to make it so the brown stripe extends 100% of the page. I want the leaf and raindrop to stay put.

Any help is appreciated.
