Node: css,images not working fine upon loading php script

Question

Hi Tried few tutorials on running php on node from this site scriptol.com so I was successful on loading the page but the problem is that some of the images did not loaded and the css rule is not also running any idea why?

Here is my code for running the server under node:

    http = require("http"),  
path = require("path"),  
url = require("url"),  
fs = require("fs");  

function sendError(errCode, errString, response)
{
    response.writeHead(errCode, {"Content-Type": "text/plain"});  
    response.write(errString + "\n");  
    response.end(); 
    return; 
}

function sendFile(err, file, response) 
{  
  if(err) return sendError(500, err, response);
  response.writeHead(200);  
  response.write(file, "binary");  
  response.end();    
}  

function getFile(exists, response, localpath)
{
  if(!exists) return sendError(404, '404 Not Found', response);
  fs.readFile(localpath, "binary", 
    function(err, file){ sendFile(err, file, response);});   
}

function getFilename(request, response)
{  
    var urlpath = url.parse(request.url).pathname; // following domain or IP and port  
    var localpath = path.join(process.cwd(), urlpath); // if we are at root 
    path.exists(localpath, function(result) { getFile(result, response, localpath)});  
}

var server = http.createServer(getFilename);
server.listen(1000);  
console.log("Server available...");  

I have also made sure that all the files are existing, Please help Thanks!
