Same image, same code, different results!!

Question

Hi,
I have this HUGE dilema, the following works with a gif or a jpg image but the problem occurs in png images (the format I have chosen to create my images in).
Here is the source code for the applet:
* bufferstr.java
* Created on 23 October 2003, 14:03
* @author  Ahmed
package Destruction_BufferStrategy;
import java.awt.*;
import java.awt.image.*;
import java.awt.event.*;
import javax.swing.*;
public class appletExecutor extends JApplet {
    private Image offs;
    private Graphics2D g2;
    ImageLoader imageStore;
    Game game;
    public void init() {
        imageStore = new AppletImageLoader();
        imageStore.prepareImage("car2dirty1.PNG");
        imageStore.prepareImage("car2dirty2.PNG");
        imageStore.prepareImage("car2dirty3.PNG");
        imageStore.prepareImage("car2dirty4.PNG");
        imageStore.prepareImage("car2dirty5.PNG");
        game = new Game(imageStore, this.getSize().width, this.getSize().height);
        super.getContentPane().add(game);
        game.startThread();
        game.createStrategy();
        game.requestFocus();
}and here is the code for the application:
* appExecutor.java
* Created on 25 October 2003, 01:08
package Destruction_BufferStrategy;
* @author  Ahmed
import java.awt.*;
import java.awt.image.*;
import java.awt.event.*;
import javax.swing.*;
public class appExecutor extends JFrame {
    private Image offs;
    private Graphics2D g2;
    ImageLoader imageStore;
    Game game;
    public appExecutor() {
        super("Destruction Derby");
        setDefaultCloseOperation(super.EXIT_ON_CLOSE);
        setResizable(false);
        setBounds(0, 0, 600, 600);
        imageStore = new AppletImageLoader();
        imageStore.prepareImage("car2dirty1.PNG");
        imageStore.prepareImage("car2dirty2.PNG");
        imageStore.prepareImage("car2dirty3.PNG");
        imageStore.prepareImage("car2dirty4.PNG");
        imageStore.prepareImage("car2dirty5.PNG");
        game = new Game(imageStore, 600, 600);
        getContentPane().add(game);
        show();
        game.startThread();
        game.createStrategy();
    public static void main(String[] args) {
        new appExecutor();
}if I use a jpg or a gif image, everything is as good as gold. However, when I use png images, this error occurs in the applet only:

Error Loading Image: car2dirty1.png
the Error Loading Image: car2dirty1.png is from my Loading Images class which abuse so kindly showed me the light to.
any help on this issue is of great appreciatence..
P.S. the error occurs for every image, not just this one!!

Answer 1

You don't actually show the method you are using to load your image, however from the error msg, I assume you are using ImageIO.read().
What version of JRE are you using?
The reason I ask, is because the error you are getting seems to be occuring at quite low-level; the only potencial cause I know of (outside an error of your creation) is the ImageIO loader in 1.4.0 is buggy/broken when dealing with small images.
