How to get an image into an app?

Sorry to bother everyone yet again but I have a problem that is really annoying me. Our teacher wants us to make a calculator, which I have done, and wants us to put as many different features into it as possible. As a suggestion he said we should have an "About" thing with stuff like Version Number, Creator, etc and a picture. Now I am trying to use a JLabel as an icon, which apparently you can do with its constructor "JLabel(Icon image)", I have looked all over for how you acomplish this but I have had no luck.

Short version: How do you put an image into your java app?

My code if it will help:

package mycalculator;

import java.awt.*;
import java.awt.event.*;
import javax.swing.*;

public class AboutForm extends JFrame implements ActionListener{

public AboutForm(){
super("About");
this.setDefaultCloseOperation(EXIT_ON_CLOSE);
this.setSize(300, 300);
Font f = new Font("Trebuchet MS", Font.PLAIN, 13);
Font f2 = new Font("Trebuchet MS", Font.BOLD, 16);

this.setFont(f);
BorderLayout b1 = new BorderLayout();
GridLayout g = new GridLayout(4, 1);
JButton btn1 = new JButton("CLICK HERE");
btn1.setFont(f);

JButton btn2 = new JButton("CLICK HERE ALSO");
JPanel panel = new JPanel();
JLabel lbl = new JLabel();
JLabel lbl2 = new JLabel();

ImageIcon icon = new ImageIcon("images/b.gif");
JLabel lblImg = new JLabel(icon);

panel.setSize(100,100);
panel.setLayout(g);
panel.add(lblImg);
panel.add(lbl2);
this.getContentPane().add(panel, BorderLayout.CENTER);

}

I have my image in a folder in NetBeansProjects\myCalculator\src\mycalculator\images, is this the right place to put it?

Any help is greatly appreciated.

File location is incorrect, move it to: NetBeansProjects\myCalculator\images

Please Use Code Tags.

Apart from the code tags, it would have been better to post on the Swing forum. I shall move you there.

if you want to include your image in your submitted work, you may have to .jar it
and load the image via a getResource()

Thank you! It was just the location of the image, now it works.

Thanks also for the other advice, I'll be sure to use the tags in any future posts and I'll put any other swing-related things in the swing forum.
