Easy image question

Question

Hi there, I am currently learning java and need help with this problem i am having. For some reason when i try and display an image in this user interface nothing comes up. Ive tried various different images and have made sure the image is in the same directory as the java file. Any ideas?
import javax.swing.*;
import java.awt.*;
import java.awt.event.*;
public class Super extends JFrame{
private static String clicks = "Number of clicks... ";
private int numClicks = 0;
public Component createComponents() {
final JLabel clicksLabel = new JLabel(clicks + numClicks);
// Create labels and buttons, then add them in a pane
JLabel titleLabel = new JLabel(new ImageIcon("images/fatboy.gif"));
JButton searchButton = new JButton("Search");
searchButton.setToolTipText("Click me!");
searchButton.setMnemonic('S');
searchButton.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent e) {
numClicks++;
clicksLabel.setText(clicks + numClicks);
JPanel pane = new JPanel();
pane.setBorder(BorderFactory.createEmptyBorder(25,20,20,20));
pane.setLayout(new GridLayout(0,1));
pane.add(titleLabel);
pane.add(clicksLabel);
pane.add(searchButton);
return pane;
public static void main(String[] args) {
// Set the look and feel
try {
UIManager.setLookAndFeel(
UIManager.getCrossPlatformLookAndFeelClassName());
} catch (Exception e){}
//Add top level layer and add components
JFrame frame = new JFrame("W E L C O M E");
Super app = new Super();
Component contents = app.createComponents();
frame.getContentPane().add(contents, BorderLayout.CENTER);
//finish setting up the frame and set it
frame.addWindowListener(new WindowAdapter() {
public void windowClosing(WindowEvent e){
System.exit(0);
frame.pack();
frame.setVisible(true);
} // end class Gui

There's little or no reason to ever subclass JFrame -- subclassing is done to override methods, right? -- but people do it out of laziness, they turn it into their top-level "application class".
Anyway, here is a short program that displays another "fat boy"
import java.awt.*;
import java.io.*;
import java.net.*;
import javax.swing.*;
public class ImageDemo {
    public static void main(String[] args) throws IOException {
        JFrame f = new JFrame("ImageDemo");
        URL url = new URL("http://java.sun.com/people/jag/images/JamesWavingFlashlightInSydneyMed.jpeg");
        ImageIcon icon = new ImageIcon(url);
        if (icon.getImageLoadStatus() != MediaTracker.COMPLETE)
            throw new IOException("failed to load: " + url);
        f.getContentPane().add(new JLabel(icon));
        f.pack();
        f.setLocationRelativeTo(null); //centre on screen
        f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        f.show();
}URLs work with protocol file, too, so you could write
URL url = new URL("file:pic.gif"); //in same directory
URL url = new URL("file:images/pic.gif"); //subdirectoryWhen I'm loading a file from a relative path, I prefer to do it like this:
URL url = ImageDemo.class.getResource("images/pic.gif");because this code will continue to work if I zip the class and image files into a jar, which is a convenient way to package an app.
