Who won't my "@media screen" kick in correctly?

I'm putting a mobile version of my website together and I'm using the @media screen dynamic to ensure my screens are properly formatted for phones and tablets.

In the past, I've only concerned myself with phones and that may be why whatever I'm doing now didn't surface as a problem, because now with the additional sizes, I'm running into trouble.

Currently I've got my stylesheet set up like this:

@media screen and (max-width: 480px) {
#header_graphic {
height:84px;
width:480px;
margin:auto;
text-align:center;
background-image:url(images/header_logo_480.png);
background-repeat:no-repeat;
}
}

@media screen and (max-width: 320px) {
#header_graphic {
height:84px;
width:480px;
margin:auto;
text-align:center;
background-image:url(images/header_logo_320.png);
background-repeat:no-repeat;
}
}

@media screen and (max-width: 768px) {
body {
height:84px;
width:768px;
margin:auto;
text-align:center;
background-image:url(images/header_logo_768.png);
background-repeat:no-repeat;
}
}

@media screen and (max-width: 1024px) {
body {
height:84px;
width:768px;
margin:auto;
text-align:center;
background-image:url(images/header_logo_1024.png);
background-repeat:no-repeat;
}
}

Seems right, yeah?

If you head out to http://www.brucegust.com/NHBC/mobile/about.php, you'll see my header graphic is way too stinkin' big. The images are in place and they are accurate, but instead of a header graphic that's 320px across, I'm getting one that's way bigger.

What am I doing wrong?

Order your queries from largest to smallest, because at the moment you have
max-width: 1024px
as the last query and that is true for all screen sizes upto that width negating your prior queries for smaller screen sizes

Either that or specify the min width as well (1px more than the smaller width) e.g.

min-width:769px and max-width: 1024px
This way only the query satisfying the screen size will be used.
