background-image:url(/pix/smile.gif);
background-repeat:no-repeat;

but maybe you want the image fixed

background-image:url(/pix/smile.gif) Fixed;

Could you please let us know the theme your using, because if you want a site background image you have to make areas of the themes architecture transparent as well.

Such as the Origin theme would need this code.

.ow_header {
background: transparent!important;
}
.ow_page_container {
background:transparent!important;
}
.ow_page_container .ow_page {
background:transparent!important;
}
.ow_page_wrap
{background:url("URL path to your image file")fixed;
}
.ow_footer{
 background:transparent!important;
} 

The basic theme this code

.ow_header {
background: transparent;
}
.ow_page_container {
background:transparent!important;
}
.ow_page_container .ow_page {
background:transparent!important;
}
body
{background:url("path to your background image")fixed;
}
.ow_footer{
 background:transparent!important;

I am using the default theme!

Topic was moved from General Questions.

So that's the origin theme

.ow_header {
background: transparent!important;
}
.ow_page_container {
background:transparent!important;
}
.ow_page_container .ow_page {
background:transparent!important;
}
.ow_page_wrap
{background:url("URL path to your image file")fixed;
}
.ow_footer{
 background:transparent!important;
} 

Ok I got the image to fit the screen but I would like it to fit the screen no matter what size the screen  if you look at my site www.poledust.com when you scroll down the back ground image repeats again like it starting over but I would like it to seem endless!
Thanks for the code above it works great I dont mind if the header of footer show so I didnt use that part of the code thanks for your help!

Basically to get a site to fit any screen size all measurements should be percentages and not pixels.  

Your site looks fine in every screen display mode but at 800 x 600 the scroll bar appears. 

I am looking to do the same thing as Jon but with the biohazard theme instead, can you help me? How do you change the pixels to percentages?

neither poledust.com or photodrain.com seem to load..

Quote from Taylor biohazard

Biohazard background is already by default set proper..

body, body.ow {    

background-color: #0D1422;

background-image: url("images/page_bg_image.jpg");

background-repeat: repeat;}

Anyone?

I believe this is the effect you are after.

This virtually impossible within Oxwall without custom coding and the next update will most like overwrite your custom code.

.ow_page_wrap {
    position: relative;
    background-image: url('image/image.png');
    background-repeat:no-repeat;
    background-attachment:fixed;
    background-size: cover;
    width: 100%;
    height: auto;
