Something like this

ImageIcon icon = new ImageIcon();
                Image image = Toolkit.getDefaultToolkit().createImage("onepixel.gif");
                icon.setImage(image);
if (icon.getImageLoadStatus == MediaTracker.ABORTED) {
   ImageIcon newIcon = new ImageIcon();
}


in this case wont mediaTrackerId starts from 0 again for "newIcon"?
