JScrollPane ! Same thing with ScrollPane. Help is wanted and
aprreciated!

import java.awt.*;
import java.awt.image.*;
import javax.swing.*;

public class myFrame extends JFrame {
 JScrollPane scrollPane;
 myCanvas c;
 public myFrame(){
  c = new myCanvas();
  scrollPane = new JScrollPane(c);
  this.getContentPane().add(scrollPane);
 }

 public static void main(String args[]){
  myFrame f = new myFrame();
  f.setSize(200, 300);
  f.setVisible(true);
 }
}

class myCanvas extends Canvas{
 Image img;

 public myCanvas(){
  //you may change image to your own
  img = Toolkit.getDefaultToolkit().getImage("AboutSwing.gif");
 }

 public void paint(Graphics g){
  g.drawImage(img, 0, 0, this);
 }
}
