That's for the JLabel right? ... For a JPanel on a JFrame, you could do something like this:
import java.awt.*;
import java.awt.image.*;
import javax.swing.*;
import javax.swing.event.*;
import java.io.*;
import java.net.URL;
public class TestImagePaint  extends JFrame {
  private BjPanel bjp;
  public TestImagePaint( String imageName )   throws IllegalArgumentException {
    if ( imageName == null  ||  !( new File( imageName ).isFile() ) ) {
      throw new IllegalArgumentException( "\nIn TestImagePaint constuctor"
                                         +"\t IllegalArgumentException:" );
    bjp = new BjPanel( imageName );
    getContentPane().add( bjp );
    setDefaultCloseOperation(EXIT_ON_CLOSE);
    pack();
    setBounds( 100, 100, 400, 300 );
    setVisible( true );
  public static void main( String[] argv ) {
    new TestImagePaint( argv[0] );
  public class BjPanel  extends JPanel {
    private URL   url;
    private Image image;
    public BjPanel( String imageName ) {
      try {
        url   = BjPanel.class.getResource( imageName );
        image = Toolkit.getDefaultToolkit().getImage( url );
        repaint();
      catch( Exception e ) {
        System.out.println( "Can't get Image: "+imageName+"\n\t"+e );
        System.exit( -1 );
    public void paint(Graphics g) {
      g.drawImage( image, 0, 0, this );
}
