Why doesn't my picture get shown?

Question

I want a picture to show up on my GUI, but I have no idea how to go about it. This is what I've tryed so far, and it compiles. But it doesnt show the picture when I compile. What am I doing wrong?
import java.awt.*;
import javax.swing.*;
public class Piccy extends JFrame{
Image ball;
   public Piccy() {
   super();
   Toolkit kit = Toolkit.getDefaultToolkit();
   ball = kit.getImage("chaz.gif");
   public void paintComponent(Graphics comp) {
      JPanel north = new JPanel();
          Graphics2D comp2D = (Graphics2D) comp;
      comp2D.drawImage(ball, (int)100, (int)100, this);
      this.getContentPane().add(north, BorderLayout.SOUTH);
   public static void main(String[]args)
      JFrame f = new Piccy();
      f.setVisible(true);
      f.setSize(500,500);

Answer 1

'cause your code's kinda a mess!
You make a new JFrame in your main method, set its size and show it - which is what happens when you run this code.
You have your main class extend JFrame, but you never call its show method, and you do a bunch of work in a paintComponent method that, as near as I can tell, doesn't get called. Maybe you were wanting to override the method in some subclass of JComponent? Like your JPanel there? But even so, adding a component from within a paint method doesn't sound like a good idea to me.
Check tutorials - hit Google (I found this: http://cit.wta.swin.edu.au/cit/subjects/CITP0014/tutorials/netbeans/graphics/graphics.html )
