        btnNewButton.addActionListener(new ActionListener() {

            @Override
            public void actionPerformed(ActionEvent e) {
                img = Toolkit.getDefaultToolkit().createImage(ImageWindow.this.getClass().getResource("test.png"));
                ImageWindow.this.repaint();

    }

    public void paintComponent(Graphics g) {
        if (img != null) {
            g.drawImage(img, 0, 0, this);
        }
    }
}

hope this helps :)
