PLEASE HELP ME to put an image over a background image !!

Question

Hello,
I need help on my AWT program. I have a map being displayed, and would like an image of a car (car.gif) to be displayed over the image of the map.
So my question is: How do I make this map a background image, and put the picture of the car right over it. I need my map loaded all the time, and the picture of the car will be reloaded many times over the same map, so a class method to load this map would be perfect. Any help, code, or suggestions would be great. Thanks so much!
Here is what I currently have for my map.
import java.awt.*;
import java.awt.event.*;
public class MyImage extends Panel {
    private Image im = null;
    Graphics g;
    public void getMap(){
      im = Toolkit.getDefaultToolkit().getImage("C:\\test_map.gif");
         MediaTracker tracker = new MediaTracker(this);
         tracker.addImage(im,0);
         try {
             tracker.waitForID(0);
         }catch (InterruptedException e){}
             repaint();
   public void paint(Graphics g){
        this.g = g;
         if (im != null)     {
            g.drawImage(im,0,0,this.getWidth(),this.getHeight(),this);  //706,397
    }

Look at this sample, the car will start when the button will be pressed, and stop on the next press.
