ImageObserver and rescaled image

Question

Hi,
I got a custom JFileChooser, where the user can see image previews.
The little problem is, for large images, the rescale-method takes a few seconds to show the
image on the custom view component. How can i(in general for unscaled pictures too) show the
current status of the image(maybe during rescaling).
regards.

ok, so now I have:
public class Goomba implements java.awt.image.ImageObserver
That gives me an error that: Goomba should be declared abstract; it does not define
imageUpdate(java.awt.image, int, int, int, int, int) in Goomba
So I tried putting imageUpdate(gi, 0, pos_x, pos_y, 50, 50) .........and I still get the same error.
If this helps, heres the code in question:
import java.applet.*;
import java.awt.*;
import java.util.*;
import java.net.*;
public class Goomba implements java.awt.image.ImageObserver
     private int pos_x;
     private int pos_y;
     private int x_speed;
     private int first_x;
     private int first_y;
     private int maxspeed;
Image gi;     
     private final int x_leftout = 25;
     Player player;
//calls this everytime we want a new goomba
// x is the x position
// y is the y position
// vx is the speed
// player is the player
// goomba_image is the actual image of the goomba
     public Goomba (int x, int y, int vx, Player player, Image goomba_image)
          pos_x = x;
          pos_y = y;
          first_x = x;
          first_y = y;
          x_speed = vx;          
gi = goomba_image;
          this.player = player;
//--------------------cut out the rest of the code for Goomba ---------------------
     public void DrawGoomba(Graphics g)
//tried this when it gave me the imageUpdate error:
//imageUpdate(gi, 0, pos_x, first_y, 50, 50);
          g.drawImage(gi, pos_x, first_y, 50, 50, this);
}
