How to vertically strech a background image?

Why would you want to do this with your HTML? I would use Photoshop or a design program to stretch my image and then make it my background....

You can't, you would have to make it repeat or do what chump said.

I wanted it so it fits all resolutions :(

The most you can do is have it centered and have a background color that matches a dominant color in the image to make it appear like its resizing.
<style type="text/css">
body {
background-image:url(yourimage.jpg);
background-position:center;
background-repeat:no-repeat;
background-attachment:fixed;
background-color:#000000 /*this should match a dominant color in your image*/
}
</style>
The shorthand version of that would be
<style type="text/css">
body {
background:#000000 url(yourimage.jpg) no-repeat fixed center;
}
</style>
