Answer 1

change this

if(ae.getSource() == submit)
    {

        pictures = new ImageIcon("galileo2.jpg");
        images = new JLabel(pictures);

        System.out.println("test");
    }

to

if(ae.getSource() == submit)
    {

        pictures = new ImageIcon("galileo2.jpg");
        images.setIcon(pictures);

        System.out.println("test");
    }
