It's always good to send an example as you finally did.
That helps to find a solution:
package applet;
import javax.swing.*;
import java.awt.*;
public class backgammon extends JApplet{
    public Icon pulicon,bgIcon;
    private Image pul_s,background;
    public JButton b1;
    public void init(){
        //set layout:
        getContentPane().setLayout(null);
        this.setSize(744, 536);
        //set button:
        pul_s = getImage(getCodeBase(),"images/pul_sari.gif");
        pulicon = new ImageIcon(pul_s);
        b1 = new JButton(pulicon);
        b1.setBounds(50,50,42,42);
        b1.setContentAreaFilled(false);
        b1.setBorderPainted(false);
        getContentPane().add(b1);
        //set background:
        background = getImage(getCodeBase(),"images/background.jpg");
        bgIcon = new ImageIcon(background);
        JLabel bg = new JLabel(bgIcon);
        bg.setBounds(0,0,getWidth(),getHeight());
        getContentPane().add(bg);
}
