I am trying to generate a random image everytime someone clicks spin. I am not able to generate a random picture. Some help would be really nice. Thanks in advance. Here's my code so far :

import java.awt.*;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import java.util.Random;

import javax.swing.*;

public class Gui {

    private JFrame frmCarlAlphoncesLab;
    private JLabel _lblNewLabel_1;
    private JLabel _lblNewLabel_2;
    private JLabel _lblNewLabel;
    private JButton btnSpin;

    /**
     * Launch the application.
     */
    public static void main(String[] args) {
        EventQueue.invokeLater(new Runnable() {
            public void run() {
                try {
                    Gui window = new Gui();
                    window.frmCarlAlphoncesLab.setVisible(true);
                } catch (Exception e) {
                    e.printStackTrace();
                }
            }
        });
    }

    /**
     * Create the application.
     */
    public Gui() {
        initialize();
    }

    /**
     * Initialize the contents of the frame.
     */
    private void initialize() {
        frmCarlAlphoncesLab = new JFrame();
        frmCarlAlphoncesLab.setTitle("Carl Alphonce\u2019s Lab 8");
        frmCarlAlphoncesLab.setBounds(100, 100, 450, 300);
        frmCarlAlphoncesLab.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        frmCarlAlphoncesLab.getContentPane().setLayout(null);

        btnSpin = new JButton("SPIN");
        btnSpin.setBounds(159, 124, 89, 23);
        frmCarlAlphoncesLab.getContentPane().add(btnSpin);

        _lblNewLabel_1 = new JLabel("");
        Image img1 = new ImageIcon(this.getClass().getResource("/Purple.png")).getImage();
        _lblNewLabel_1.setIcon(new ImageIcon(img1));
        _lblNewLabel_1.setBounds(184, 48, 40, 40);
        frmCarlAlphoncesLab.getContentPane().add(_lblNewLabel_1);

        _lblNewLabel_2 = new JLabel("");
        Image img2 = new ImageIcon(this.getClass().getResource("/Green.png")).getImage();
        _lblNewLabel_2.setIcon(new ImageIcon(img2));
        _lblNewLabel_2.setBounds(83, 48, 40, 40);
        frmCarlAlphoncesLab.getContentPane().add(_lblNewLabel_2);

        _lblNewLabel = new JLabel("");
        Image img = new ImageIcon(this.getClass().getResource("/Red.png")).getImage();
        _lblNewLabel.setIcon(new ImageIcon(img));
        _lblNewLabel.setBounds(285, 48, 40, 40);
        frmCarlAlphoncesLab.getContentPane().add(_lblNewLabel);

        EventHandler event = new EventHandler();
        btnSpin.addActionListener(event);

    }

    public class EventHandler implements ActionListener {
        private String[] Images = { "Green.png", "Purple.png", "Red" };
        Random rand = new Random();

        public EventHandler(){

        }
        @Override
        public void actionPerformed(ActionEvent e) {

            if(e.getSource()==btnSpin){
                Integer a = (int) (Math.random() * 3);
                Image myImg = Toolkit.getDefaultToolkit().getImage(Images[a]);
            System.out.println("HERE");
            }
        }

    }

}

Are you getting random numbers? You should System.out.println() that to see if that is the issue or something else.

I need to generate random pictures when spin button is clicked not numbers

In your function it generates a (hopefully) random number. I noted you need to check that first. Have you?

Pictures (in digital form) are nothing but numbers. If you are generating random numbers then you can generate random pictures.
