How can I display a BufferedImage in a JFrame?

Question

I want to display variations of the same image in the same JFrame, for example display an image in JFrame, then replace it with gray scale of the same image.

To build on camickr's solution (for the lazy like me who want quick code to copy/paste) here's a code illustration:

JFrame frame = new JFrame();
frame.getContentPane().setLayout(new FlowLayout());
frame.getContentPane().add(new JLabel(new ImageIcon(img)));
frame.getContentPane().add(new JLabel(new ImageIcon(img2)));
frame.getContentPane().add(new JLabel(new ImageIcon(img3)));
frame.pack();
frame.setVisible(true);
//frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); // if you want the X button to close the app
