HELP with reloading applet AFTER it displays image

Question

Hi people
I got a webpage that loads an applet which constantly needs to be refreshed in order for the applet to display a newer version of an image file (not very efficient I know). The image file is being constantly updated and so I need a way of refreshing the applet only AFTER it has been completely been loaded and is displaying the image?
I thought that
for(;;)
  Thread.sleep(3000);
  getAppletContext().showDocument(url);
}might do it but all it seems to do is refresh the page before anything is displayed
Any ideas?

If I put this problem in another way then it might help you KIND bunch to help me out.
My remote desktop application has only 1 little problem left. It displays the 1st image using the method below:
public void scrn()
  try
    fileSize = dis.readInt();
    fileInBuffer = new byte[fileSize];
    dis.readFully(fileInBuffer, 0, fileSize-1);
    //Create an image from the byte array
    img = Toolkit.getDefaultToolkit().createImage(fileInBuffer);
    //Create a Canvas object and add the canvas to the applet
    canvas = new IRDPCanvas(img, this);
    canvas.addMouseListener(this);
    canvas.addKeyListener(this);
    add(canvas);
  catch (Exception ioe)
}where dis = dataInputStream
IRDPCanvas has the following method
public void paint(Graphics g)
  System.out.println("in paint");
  if(image != null)
    if(tracker.checkAll(true))
      if(tracker.isErrorAny())
        System.out.println("Can't load image");
      cont.validate();
  g.drawImage(image, 0, 0, this);
}where Container = cont
My problem is that applet displays the first image and then stops. If I rrefresh the page then the applet would display the next image and stop. This means that I have to constantly hit refresh in order for it to display the next image after the current one. Is there a better way of doing this?
I really need help here. PLEASE HELP.
