Updating image of a JLabel

Question

Hey all, I've been having some problems with repainting a JLabel with a new Image, I've looked at some other threads of this incident, but none of their solutions are working for me, any help appreciated. Code I'm currently using:
Image img = Toolkit.getDefaultToolkit().createImage("Status1.gif");
lblPicture.setIcon(new ImageIcon(img));
lblPicture.repaint(); What happens is when the action occurs the Label gets repainted to nothing, no Exceptions or anything of the sort.

Whipped up a demo anyway:
import java.awt.*;
import java.awt.event.*;
import java.io.*;
import java.net.*;
import javax.swing.*;
public class IconTest {
    public static void main(String[] args) {
        EventQueue.invokeLater(new Runnable(){
            public void run() {
                new IconTest().go();
    void go() {
        JPanel cp = new JPanel();
        cp.add(label);
        cp.add(init("bronze"));
        cp.add(init("silver"));
        cp.add(init("gold"));
        cp.add(init("krap"));
        JFrame f = new JFrame();
        f.setContentPane(cp);
        f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        f.pack();
        f.setLocationRelativeTo(null);
        f.setVisible(true);
    Icon empty = new EmptyIcon();
    JLabel label = new JLabel(empty);
    JButton init(String text) {
        try {
            JButton btn = new JButton(text);
            final URL url = new URL("http://forums.sun.com/im/" + text + "-star.gif");
            btn.addActionListener(new ActionListener(){
                public void actionPerformed(ActionEvent evt) {
                    ImageIcon icon = new ImageIcon(url);
                    System.out.println(icon.getImageLoadStatus());
                    boolean ok = icon.getImageLoadStatus() == MediaTracker.COMPLETE;
                    label.setIcon(ok ? icon : empty);
            return btn;
        } catch (MalformedURLException e) {
            throw new RuntimeException(e);
class EmptyIcon implements Icon {
    public int getIconWidth() {return 16;}
    public int getIconHeight() {return 16;}
    public void paintIcon(Component comp, Graphics g, int x, int y) {
        g.setColor(Color.RED);
        g.drawLine(x, y, x+15, y+15);
        g.drawLine(x, y+15, x+15, y);
        g.drawRect(x, y, 15, 15);
}
