images nt displaying in jade on node.js

I included css file in jade template file designed for node.js server as below:

title Home page
style
  include homepage.css

The images included in the css file are not dislayed when I render the jade file using node.js server as below:

var express=require('express');
var app=express();
app.set('view engine','jade');
app.get('/',function (req,res) {
res.render('homepage1.jade');   
});
app.listen(3000);

The css file is:

html, body, h1, h2, h3, h4, h5, p, ol, ul, li { 
}
body {font-size: 100%; font-weight: normal;  width:1365px; margin:auto;
}

#container { background-image: url("/views/technowiz_resized.jpg"); background-attachment:fixed;
}
header { width:1305px; height:100px; background-color:red; background-image:url(/views/ban_resized.png) ; text-align:center; border:10px solid black ; margin:auto;
}
#rosette { position:relative; right:550px; top:-80px;
}
footer
{
background-color:black;
border:3px solid white;

}




#sidebar 
{
    float: right;
    width: 400px;
}

#sidebar ulsb
{
    margin: 0;
    padding: 0;

list-style: none;
}

#sidebar lisb ulsb 
{

    padding: 20px;
}

#sidebar lisb lisb 
{
    padding: 2px 0;
    border-bottom: 1px dotted #333;

}


#sidebar h2sb 
{
    height: 35px;
    margin: 0;

    padding: 6px 0 0 20px;
    background: url(/views/post_title_bg.png) repeat-x;
    font-size: 153.9%;
    font-weight: normal;
    color: black;
}

#sidebar h5
{
    height: 25px;
    margin: 0;

    padding: 5px 0 0 5px;
    background: url(/views/post_title_bg.png) repeat-x;
    font-size: 110.9%;
    font-weight: normal;

    color: black;
}

#sidebar .pad 
{
    padding: 20px;
}

The background colour is loaded but not the images.

The views direcctory contains the jade css files and all the images and te project folder contains the home.js file and the views folder.

The images donot load even when /views is not specified i.e. even if only directly post_title_bg.png is written in url.

Any help would be great.Thanks.
