      Hi there,
      I'm new to JBuilder 9 and have had school experience with using JAVA.

      I am trying to display a .jpg file.

      I already have loaded it with:
      -------------------------
      Image image = null;
      // Read from a file
      File file = new File("C:\\FILES\\martian_girlfriend.jpg");
      image = ImageIO.read(file);
      -------------------------- 

      How do I now display the loaded image? I already have gotten it to
work
      and load in a separate frame, but I am looking to load it into another
      SWING component like JScollPane or other. This might not be possible
      since I'm such a Newbie and do not know the full power of Swing.

      So please send help.
      Thanks,
      Melanie.

The easiest way to display an image is using a JLabel.  You could
certainly use the code above to load the image, but there is an easier
approach using the ImageIcon class:

   Icon icon = new ImageIcon( "C:\\FILES\\martian_girlfriend.jpg" );
   JLabel label = new JLabel( icon );

Note that this assumes that you want to load the image from a *file*.
If the image is a static part of your application, you will probably
want to store the image along with your code (typically in a jar file),
and then create the Icon using the ImageIcon(URL) constructor.

Yup.

Got it work late last night.
Here's the code for the other newsbies:

 void jButton1_actionPerformed(ActionEvent e)
  {
    Image image = null;

    ImageIcon icon=new ImageIcon
        (Toolkit.getDefaultToolkit().createImage("C:\\FILES\\finger1.jpg"));

    jLabel1.setIcon(icon);
    this.repaint();

   Image image1 = null;
   try {
      // Read from a file
      File file = new File("C:\\FILES\\martian_girlfriend.jpg");
      image1 = ImageIO.read(file);
   } catch (IOException ee) {
  }

  // Use a label to display the image
  JFrame frame = new JFrame();
  JLabel label = new JLabel(new ImageIcon(image1));
  frame.getContentPane().add(label, BorderLayout.CENTER);
  frame.pack();
  frame.setVisible(true);
  }
}
