import java.awt.*;
import java.awt.event.*;public class ImageTestApplication extends Frame{
Insets insets;
Image im;

static public void main(String args[]){
ImageTestApplication app = new ImageTestApplication();
app.show();
}

public ImageTestApplication(){
super("Image Test");
im = Toolkit.getDefaultToolkit().getImage("flower.jpg");

addWindowListener(new WindowAdapter(){
public void windowClosing(WindowEvent event){
dispose();
System.exit(0);
}
});
}

public void addNotify(){
super.addNotify();
insets = getInsets();
setBounds(100,100,217 + insets.left,321 + insets.top);
}

public void paint(Graphics g){
g.drawImage(im,insets.left,insets.top,this);
}
}
