    JOptionPane.showMessageDialog(null, new JLabel(new ImageIcon(origImg)));

    File newFile = new File("new.png");
    ImageIO.write(origImg, "png", newFile);
    BufferedImage newImg = ImageIO.read(newFile);

    JOptionPane.showMessageDialog(null, new JLabel("New", new ImageIcon(newImg), SwingConstants.LEFT));
}
