Problems With Image Display

Hi all.
I'm trying to create an Image slide show.
for those of you who knows "Objects First" book, I'm using the "Image Viewer" project there.

I've created a JPanel then...

So, I've created a new frame, and place an "Image Panel" object which is a Class from the book
"public class ImagePanel extends JComponent"

The class basically set up a place to put a Buffered Image object.

The I've Added it to the JPanel andall is ok.

The problem starts when I'm trying to add photos to the Panel..
because I'm using pack(), the Window's changing it's size to the size of the new photo, but the picture is not displayed..

here is the code.. I hope I managed to explain myself...

Oh, also "ImageFileManager" is a class which checks if the file is a photo.

private static JFileChooser fileChooser = new JFileChooser(System.getProperty("user.dir"));
    private JFrame SlideShowFrame;
     private ImagePanel SlideShowImagePanel;
    int slideShowTime = 4;

private void initializeSlideShow() {
                         
                fileChooser.setFileSelectionMode(JFileChooser.DIRECTORIES_ONLY);
                int returnVal = fileChooser.showOpenDialog(frame);

if(returnVal != JFileChooser.APPROVE_OPTION)
                    return;  
                File[] fileList = fileChooser.getSelectedFile().listFiles();
                makeSlideShow(fileList);
        
    
    }
    private void makeSlideShow(File[] fileList)
    {
        String fileName;
        OFImage currentSlideImage;
        makeSlideShowFrame();
        
        for (int i = 0; i < fileList.length; i++)  {
                currentSlideImage = ImageFileManager.loadImage(fileList[i]);
                if (currentSlideImage != null) {
                    SlideShowImagePanel.setImage(currentSlideImage);
                    SlideShowFrame.pack();
                    try {Thread.sleep(slideShowTime * 1000); } catch (Exception e) {}
                }

}
        }
  private void  makeSlideShowFrame()
  {
      SlideShowFrame = new JFrame("Slide Show");
        JPanel contentPane = (JPanel)SlideShowFrame.getContentPane();
        contentPane.setBorder(new EmptyBorder(6, 6, 6, 6));

contentPane.setLayout(new BorderLayout(6, 6));
        
        SlideShowImagePanel = new ImagePanel();
        SlideShowImagePanel.setBorder(new EtchedBorder());
        contentPane.add(SlideShowImagePanel, BorderLayout.CENTER);
       SlideShowFrame.pack();
        
        // place the frame at the center of the screen and show
        Dimension d = Toolkit.getDefaultToolkit().getScreenSize();
        SlideShowFrame.setLocation(d.width/2 - frame.getWidth()/2, d.height/2 - frame.getHeight()/2);
         SlideShowFrame.setVisible(true);
      
      
    }

If someone is willing to take a look and tell me what's wrong I will appreciate it so much.

thanks,

Giora.
