settings for background image

hello

I would like to have, un both sides of the site, some pictures
I have an 1440x900px image, with a gap in the middle of 940px (the site width)
can this background be centered always, with the site? so this gap is always behing the body of the site?

i tryed some custom CSS code that you provided in another thread, but i dont like the result
(body, html {
background: url(Enter your image address here) no-repeat center center fixed!important;
-webkit-background-size: cover!important;
-moz-background-size: cover!important;
-o-background-size: cover!important;
