See this:

import java.awt.Dimension;
import java.awt.Graphics;
import java.awt.Image;
import java.awt.image.BufferedImage;
import java.io.File;
import java.io.IOException;
import java.util.logging.Level;
import java.util.logging.Logger;
import javax.imageio.ImageIO;
import javax.swing.*;

public class ImagePanel extends JPanel{
    private BufferedImage bi;

    public ImagePanel() {  

      try {
            bi = ImageIO.read(new File("Your Image Path"));
        } catch (IOException ex) {
            Logger.getLogger(ImagePanel.class.getName()).log(Level.SEVERE, null, ex);
        }


        final JPanel panel = new JPanel(){
            @Override
            protected void paintComponent(Graphics g){
                Graphics g2 = g.create();
                g2.drawImage(bi, 0, 0, getWidth(), getHeight(), null);
                g2.dispose();
            }

            @Override
            public Dimension getPreferredSize(){
                return new Dimension(bi.getWidth()/2, bi.getHeight()/2);
                //return new Dimension(200, 200);
            }
        };

        add(panel);
    }  

        public static void main(String args[]){
            SwingUtilities.invokeLater(new Runnable() {
            @Override
            public void run() {
                ImagePanel imgPanel=new ImagePanel();
                JOptionPane.showMessageDialog(
                        null, imgPanel, "Image Panel", JOptionPane.PLAIN_MESSAGE);
            }
        });
        }
}

Tips

Don't use NULL layout (as @camickr suggested)
Use proper Layout Manager
Using this code I don't thing you need ScrollPane

Don't use null layouts!!!

A scrollpane will only work when the preferred size of the component added to the viewport is greater than the size of the viewport.

You can just add the label directly to the scrollpane, you don't need to add it to the panel first.
