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);
}

// ????????????????????????????
// ????????????????????????????
// ????????????????????????????
private void picture()
{
ImageIcon pic = new ImageIcon("images/duke.gif");
jButton1.setIcon(pic);
}

}

It could have something to do with the fact that you never call the picture
method.

You are working blind here, try this instead..

URL imageURL = this.getClass().getResource( "images/dike.gif" );
System.out.println( "imageURL: " + imageURL );
ImageIcon pic = new ImageIcon( imageURL );
....

BTW - You're subject.. 'A problem; please help' is an extremely
poor one, something like 'ImageIcon does not appear in application'
would be much better.
