Why not just add an Image in an ImageIcon in a JLabel?

Yes. where it's marked 'box' should be a JLabel with your image in it, as shown in the above example

Hi SaiSeng,

Your links seems not good : "This page is not available. " or "Sorry, the page you requested was not found. "

>> i just realise i couldnt drawImage on my top most layer...
  public void paint(Graphics g)
  {
     g.drawImage(img,0,0,null); // Image img already loaded
  }

Replace:
      public void paint(Graphics g)
      {
             g.drawImage(box, 80, 80, this);
      }

By:
      public void paint(Graphics g)
      {
                      g.drawImage(box, 80, 80, this);
                      super.paint(g); // for lightweight child components
      }

You can wait until the image is loaded:

   public void init()
   {
        box = getImage(getCodeBase(), "box.jpg");
        MediaTracker tracker = new MediaTracker(this);
        tracker.addImage(box, 0);
        try{
        tracker.waitForAll();
        }catch(Exception e){e.printStackTrace();}

Using an ImageIcon will get you out of all the little gotchas caused by Java loading its images aynchronously, apart from saving you having to rewrite your JPanel as a JPanel subclass
