    Hey,
    don't have good explanation, and haven't worked with applets much, but added a [code]cont.paintComponents(g);[/code] and got the buttons to show. Program was modified slightly
    [code]
    import javax.swing.*;
    import java.awt.*;
    import java.awt.event.*;

    public class sampleimage extends JApplet implements ActionListener {

    JButton b1;
    JButton b2;
    JButton b3;

    Container cont;

    boolean home = false;
    boolean start = false;
    boolean credits = false;

    boolean a = false;
    boolean b = false;
    boolean c = false;

    Image welcome;
    MediaTracker mt;

    public void init() {

    mt = new MediaTracker(this);

    // System.out.println(this.getCodeBase());

    welcome = this.getImage(this.getCodeBase(), "Penguins.jpg");

    b1 = new JButton("START");
    b1.setActionCommand("b1");

    b2 = new JButton("CREDITS");
    b2.setActionCommand("b2");

    b3 = new JButton("BACK");
    b3.setActionCommand("b3");

    cont = getContentPane();
    cont.setLayout(null);
    cont.add(b1);
    b1.setVisible(true);
    cont.add(b2);
    cont.add(b3);

    cont.setVisible(true);

    b1.setBounds(150, 100, 75, 50);
    b2.setBounds(150, 200, 75, 50);
    b3.setBounds(150, 300, 75, 50);

    b1.addActionListener(this);
    b2.addActionListener(this);
    b3.addActionListener(this);

    } // Init end

    public boolean isOptimizedDrawingEnabled() {
    return false;
    }

    public void actionPerformed(ActionEvent ae) {

    String x = ae.getActionCommand();
    if (x.equals("b1")) {
    start = true;
    credits = false;
    home = false;
    b1.setVisible(false);
    b2.setVisible(false);
    b3.setVisible(true);
    }
    if (x.equals("b2")) {
    start = false;
    credits = true;
    home = false;
    b1.setVisible(false);
    b2.setVisible(false);
    b3.setVisible(true);
    }
    if (x.equals("b3")) {
    start = false;
    credits = false;
    home = true;
    b1.setVisible(true);
    b2.setVisible(true);
    b3.setVisible(false);
    }
    repaint();
    }

    public void paint(Graphics g) {

    home = true;

    if (home) {

    // g.drawImage(welcome, 85, 50, this);
    g.drawImage(welcome, 300, 100, this);

    }
    if (start) {

    Color car = new Color(244, 244, 244);
    g.setColor(car);
    g.fillRect(0, 0, 500, 500);
    g.clearRect(0, 0, 500, 500);
    }
    if (credits) {

    Color car = new Color(244, 244, 244);
    g.setColor(car);
    g.fillRect(0, 0, 500, 500);
    g.clearRect(0, 0, 500, 500);
    }
    cont.paintComponents(g);
    }
    }
