The picture will not appear, but why??????????
When I use a simple applet, it works.

-------------------------------------------------------------------------------------------------------------------------
package test;

public class TestClass
{

 public TestClass()
 {
 }

 public static void main(String[] args)
 {
   TestClass testClass = new TestClass();
   TestFrame test = new TestFrame();
   test.show();
 }

}
-----------------------------------------------------------------------------------------------------------------------------

package test;

import java.awt.*;
import javax.swing.*;

public class TestFrame extends JFrame
{
 JButton jButton1 = new JButton();

 public TestFrame()
 {
   try
   {
     jbInit();
   }
   catch(Exception e)
   {
     e.printStackTrace();
   }
 }

 private void jbInit() throws Exception
 {
   jButton1.setText("jButton1");
   jButton1.setBounds(new Rectangle(67, 37, 182, 114));
   this.getContentPane().setLayout(null);
   this.setSize(new Dimension(300, 300));
   this.getContentPane().add(jButton1, null);
 }

   ImageIcon pic = new ImageIcon("images/duke.gif");
   jButton1.setIcon(pic);
 }
