The getResource methods can only (as far aas I know) find resources at
the same package level as the class they are being loaded from.


here is code similar to the above code, only using a Stream to get the
file...

public static Image getImage( String name , Object object , Component
comp ) {
    try {
        // the image
        Image img = null;
        // the class to get the Image
        InputStream is =
object.getClass().getResourceAsStream( name );
        // the class to write out the Image
        ByteArrayOutputStream baos = new ByteArrayOutputStream();

        try {
            int c;
            // write out the Image file data
            while( ( c = is.read() ) >= 0 )
            baos.write(c);
            // create the Image from the Image file data
            img =
oolkit.getDefaultToolkit().createImage( baos.toByteArray() );
        }
        catch( IOException e ) {
        }
        // use the MediaTracker to load the Image
        loadGraphics( img , comp );
        return img;
    }
    catch( NullPointerException e ) {
        System.out.println("Can't find: " + name);
        return null;
    }
}
public static void loadGraphics( Image image, Component comp ) {
    MediaTracker tracker = new MediaTracker(comp);
    if( image != null )
        tracker.addImage( image , 0 );
    try {
        tracker.waitForAll();
    }
    catch( InterruptedException e ) {
    }
 }
