Displaying new image in JLabel:

Question

Hello,
I wondered if anyone could advise, how to display a new image into an Jlabel which already contains an image.
I used the this line to display the orginal image.
imageLabel = new JLabel(new ImageIcon("test.jpg"));
Thanks

This works for me:import java.awt.FileDialog;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import javax.swing.ImageIcon;
import javax.swing.JFrame;
import javax.swing.JLabel;
public class HFrame extends JFrame implements ActionListener{
     private javax.swing.JPanel jContentPane = null;
     private javax.swing.JLabel jLabel = null;
     private javax.swing.JButton jButton = null;
     public HFrame(String title){
          super(title);
          initialize();
     private void initialize() {
          this.setSize(300, 200);
          this.setContentPane(getJContentPane());
          setDefaultCloseOperation(DISPOSE_ON_CLOSE);
     private javax.swing.JPanel getJContentPane() {
          if (jContentPane == null) {
               jContentPane = new javax.swing.JPanel();
               jContentPane.setLayout(new java.awt.BorderLayout());
               jContentPane.add(getJLabel(), java.awt.BorderLayout.CENTER);
               jContentPane.add(getJButton(), java.awt.BorderLayout.NORTH);
          return jContentPane;
     public static void main(String[] args) {
          HFrame hf = new HFrame("Help");
          hf.setVisible(true);
     public void getPath(){
          FileDialog fd = new FileDialog(this,"Pick file", FileDialog.LOAD);
          fd.show();
          if (fd.getFile() == null) {
               return;
          String imagePath =  fd.getDirectory() + fd.getFile();
          System.out.println(imagePath);
          getJLabel().setIcon(new ImageIcon(imagePath));
     private javax.swing.JLabel getJLabel() {
          if(jLabel == null) {
               jLabel= new JLabel();
          return jLabel;
     private javax.swing.JButton getJButton() {
          if(jButton == null) {
               jButton = new javax.swing.JButton();
               jButton.setText("image");
               jButton.addActionListener(this);
          return jButton;
     public void actionPerformed(ActionEvent e) {
          getPath();
}
