Problem in adding image to a frame.

Question

Hi,
I am trying to add an image to a frame as follows:
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
import java.util.*;
class introFrame extends JFrame
     private Image image;
     public introFrame()
          setUndecorated(true);
          image = Toolkit.getDefaultToolkit().getImage("triplesIcon.gif");
          MediaTracker tracker = new MediaTracker(this);
          tracker.addImage(image, 0);
          try
               tracker.waitForID(0);
          catch (InterruptedException exception)
          setBounds(100,100,600,400);
          Container contentPane = getContentPane();
          contentPane.setBackground(Color.white);
          show();
     public void paintComponents(Graphics g)
          super.paintComponents(g);
          g.drawImage(image, 20, 20, null);
But it is not showing the image. The image and the class is in the same folder.
Please suggest me the solution.

public class Example {
    public static void main(String[] args) throws MalformedURLException {
        URL url = new URL("http://today.java.net/jag/bio/JagHeadshot-small.jpg");
        JLabel label = new JLabel(new ImageIcon(url));
        label.addMouseListener(new MouseAdapter(){
            public void mousePressed(MouseEvent e) {
                if (e.getClickCount() > 1)
                    System.exit(0);
        JFrame f = new JFrame("Example");
        f.setUndecorated(true);
        f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        f.getContentPane().add(label);
        f.pack();
        f.setLocationRelativeTo(null);
        f.setVisible(true);
