Hi Cinderalla,
First off there is no need to paint an image onto a JButton. It directly supports using icons (Images) instead of text. This is what makes it so much better than Button!
I seem to recall another post by someone who was trying to have a button with multiple images responding to mouse events. The code below will use a JButton extension to perform that function. Maybe it will help you with some ideas.

import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
public class IconButton extends JButton
{
  private Icon normal;
  private Icon rollOver;
  private Icon select;
  public IconButton()
  {
    super();
    MediaTracker tracker = new MediaTracker( this );
    Image normalImage = Toolkit.getDefaultToolkit().getImage( "NORMAL.GIF" );
    tracker.addImage( normalImage, 0 );
    Image rollOverImage = Toolkit.getDefaultToolkit().getImage( "ROLLOVER.GIF" );
    tracker.addImage( rollOverImage, 1 );
    Image selectImage = Toolkit.getDefaultToolkit().getImage( "SELECT.GIF" );
    tracker.addImage( selectImage, 2 );
    try
    {
      tracker.waitForID( 0 );
      tracker.waitForID( 1 );
      tracker.waitForID( 2 );
    }
    catch( InterruptedException e )
    {};
    normal = new ImageIcon( normalImage );
    select = new ImageIcon( selectImage );
    rollOver = new ImageIcon( rollOverImage );
    System.out.println( "Setting icon: " + normal );
    setIcon( normal );
    enableEvents( AWTEvent.MOUSE_EVENT_MASK );
  }
  public void processMouseEvent( MouseEvent me )
  {
    if( me.getID() == MouseEvent.MOUSE_ENTERED )
    {
      setIcon( rollOver );
    }
    else if( me.getID() == MouseEvent.MOUSE_EXITED )
    {
      setIcon( normal );
    }
    else if( me.getID() == MouseEvent.MOUSE_PRESSED )
    {
      setIcon( select );
    }
    else if( me.getID() == MouseEvent.MOUSE_RELEASED )
    {
      setIcon( normal );
    }
    super.processMouseEvent( me );
  }
  public static void main(String[] args) 
  {
    JFrame f = new JFrame( "IconButton" );
    f.getContentPane().setLayout( new FlowLayout() );
    f.getContentPane().add( new IconButton() );
    f.pack();
    f.setVisible( true );
  }
}

Enjoy,
Manfred.
