Why doesn't the .gif picture comes up?

I've written a code for a Clickable Applet.
The problem I'm having is displaying the .gif file.
The code compiles successfully and once I run the applet, the buttons work. It just that the picture doesn't show.

What I have tried:

import java.awt.*;
import java.awt.event.*;
import java.applet.*;

public class MoveIt extends Applet implements ActionListener
{
	//declare variables
	private Image cup;
	private Panel keyPad;
	public int top = 15;
	public int left = 15;
	private Button keysArray[];

	public void init()
	{
		Image cup = getImage(getDocumentBase(), "cup.gif");
		Canvas myCanvas = new Canvas();

		Panel keyPad = new Panel();
		Button up = new Button("Up");
		Button left = new Button("Left");
		Button right = new Button("Right");
		Button down = new Button("Down");
		Button center = new Button("Center");
		setBackground(Color.blue);
		setLayout(new BorderLayout());
		keyPad.setLayout(new BorderLayout());

		//Adding the Buttons
		keyPad.add(up, BorderLayout.NORTH);
		keyPad.add(down, BorderLayout.SOUTH);
		keyPad.add(right, BorderLayout.EAST);
		keyPad.add(left, BorderLayout.WEST);
		keyPad.add(center, BorderLayout.CENTER);
		add(myCanvas, BorderLayout.NORTH);
		add(keyPad, BorderLayout.SOUTH);

		//ActionListener statements
		up.addActionListener(this);
		down.addActionListener(this);
		right.addActionListener(this);
		left.addActionListener(this);
		center.addActionListener(this);
		}

        public void paint( Graphics g )
        {
            g.drawImage(cup, left, top, this );
        }

        public void actionPerformed(ActionEvent e)
        {
            String arg = e.getActionCommand();

            if(arg == "up")
                top = top - 10;
            if(arg == "down")
                top = top + 20;
            if(arg == "left")
                left = left - 10;
            if(arg == "right")
                left = left + 10;
            if(arg == "center")
                top = 60;
                left = 125;

            repaint();
	}
}
