public class MainFrame extends JFrame
JPanel jPanel1 = new JPanel();
JPanel jPanel2 = new JPanel();
JButton jButton1 = new JButton();
JButton jButton2 = new JButton();
Image image = Toolkit.getDefaultToolkit().createImage("c:\\form-3.jpg");
javax.swing.JScrollBar jScrollBar1 = new JScrollBar();
BorderLayout borderLayout1 = new BorderLayout();
public MainFrame()
try
jbInit();
} catch (Exception ex)
ex.printStackTrace();
public static void main(String[] args)
MainFrame mainFrame = new MainFrame();
private void jbInit() throws Exception
     //jbInit() defined here
public void paintComponent(Graphics g)
// jPanel1.getGraphics().drawImage(image,0,0,jPanel1);
Graphics2D g2D = (Graphics2D) g;
BufferedImage bi = (BufferedImage) createImage(getWidth(),getHeight());
bi.createGraphics().drawImage(image, 0,0, jPanel1);
// g.drawImage(image,0,0,jPanel1);
public void jButton2_mouseClicked(MouseEvent e)
     public void jButton1_mouseClicked(MouseEvent e)
this.dispose();
System.exit( 0 );

Answer 1

this works OK
(stripped of everything unrelated to your question)
import javax.swing.*;
import java.awt.*;
class MainFrame extends JFrame
  Image image = Toolkit.getDefaultToolkit().createImage("test.gif");
  public static void main(String[] args)
    MainFrame mainFrame = new MainFrame();
    mainFrame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    mainFrame.setSize(200,200);
    mainFrame.setVisible(true);
  public void paint(Graphics g)//<-----heavyweight component
    super.paint(g);
    g.drawImage(image,50,50,this);
}
