assignement change the java screensaver

I would like to change this screensaver that draw multiple lines in different and color in different positions, to a screensaver that put a picture (let's call it pict01) in the screensaver and change its position.
but i am new in java, can somebody help me

file number 1----->saver1.java

import javax.swing.JFrame;

public class Saver1
{
public static void main( String args[] )
{
// create frame for Saver1JPanel
JFrame frame = new JFrame( "Saver1" );
frame.setDefaultCloseOperation( JFrame.EXIT_ON_CLOSE );

Saver1JPanel saver1JPanel = new Saver1JPanel();
frame.add( saver1JPanel ); // add saver1JPanel to frame
frame.setSize( 300, 300 ); // set frame size
frame.setVisible( true ); // display frame
} // end main
}



file number 2-------->Saver1JPanel

import java.awt.Color;
import java.awt.Graphics;
import javax.swing.JPanel;

public class Saver1JPanel extends JPanel
{
private final int DELAY = 9999999;

// draw lines
public void paintComponent( Graphics g )
{
super.paintComponent( g ); // call superclass's paintComponent

int x, y, x1, y1;

// draw 100 random lines
for ( int i = 0; i < 100; i++ )
{
x = ( int ) ( Math.random() * 300 );
y = ( int ) ( Math.random() * 300 );
x1 = ( int ) ( Math.random() * 300 );
y1 = ( int ) ( Math.random() * 300 );

g.setColor( new Color( ( float ) Math.random(),
( float ) Math.random(), ( float ) Math.random() ) );
g.drawLine( x, y, x1, y1 );

// slow the drawing down. the body of the for loop is empty
for ( int q = 1; q < DELAY; q++ ) ;
} // end outer for

repaint(); // repaint component
} // end method paintComponent
}


thank you
