Display a background image

Question

I want to display an image into a panel and then add this panel to a frame. I used the following code but I don't know why the image doesn't appear.
Test.java :
public class Test {
private JFrame framePrincipal;
private JPanel panel;
private Toolkit toolkit = Toolkit.getDefaultToolkit();
private Image image = toolkit.getImage ("C:/ProGolf/Images/image.jpg");
public Test (){
     panel = new JPanel();
     framePrincipal=new JFrame("Club de Golf Joliette");
     framePrincipal.setBackground(new Color(185,211,238));
     ImagePanel imagePanel = new ImagePanel(image);
     panel.add(imagePanel,BorderLayout.CENTER);
     framePrincipal.setContentPane(panel);
     framePrincipal.setSize(new Dimension(650,200));
     framePrincipal.setVisible(true);
public static void main (String [] args){
     Test monTest = new Test();
ImagePanel.java :
public class ImagePanel extends JPanel {
Image image;
public ImagePanel(Image image) {
this.image = image;
public void paintComponent(Graphics g) {
super.paintComponent(g); //paint background
//Draw image at its natural size first.
g.drawImage(image, 0, 0, this); //85x62 image

Simpler than that;-import java.awt.*;
import javax.swing.*;
public class JFrameImage extends JFrame {
  public JFrameImage() {
      super("Images on a JFrame");
      Container c    = getContentPane();
      JPanel panel = new JPanel(){
             public void paintComponent(Graphics g)     {
                  ImageIcon img = new ImageIcon("myImg.jpg");
                  g.drawImage(img.getImage(), 0, 0, null);
                  super.paintComponent(g);
        panel.setOpaque(false);
      c.add(panel);
  public static void main(String[] args) {
    JFrameImage frame = new JFrameImage();
    frame.setDefaultCloseOperation( EXIT_ON_CLOSE );
    frame.setVisible(true);
// and here we have stretch to fit too!
      JPanel panel = new JPanel(){
             public void paintComponent(Graphics g)     {
                  ImageIcon img = new ImageIcon("myImg.jpg");
            ImageIcon bigImage = new ImageIcon(img.getImage().getScaledInstance
                               (getWidth(), getHeight(),Image.SCALE_REPLICATE));
            g.drawImage(bigImage.getImage(), 0, 0, this);
                  super.paintComponent(g);
        panel.setOpaque(false);
// and finally tiling
         JPanel panel = new JPanel(){
                public void paintComponent(Graphics g)     {
                  ImageIcon img = new ImageIcon("smallImage.jpg");
            int x = img.getImage().getWidth(this);
            int y = img.getImage().getHeight(this);
               for (int tileY = 0; tileY < getWidth(); tileY += y)
               for (int tileX = 0; tileX < getHeight();tileX += x)
               g.drawImage(img.getImage(), tileX, tileY, this);    
                   super.paintComponent(g);
        panel.setOpaque(false);
