Center an image in a component

Question

I am painting different size images and need to know how to center them in a component. I'm painting to a canvas object that I add to a panal Object. Not sure if this is the correct structure.
Thanks for the help

Does JLabel+ImageIcon already do that for you?
import java.awt.*;
import java.net.*;
import javax.swing.*;
public class Example {
    public static void main(String[] args) throws MalformedURLException {
        JPanel cp = new JPanel(new GridLayout(2,2));
        addImage(cp, "http://today.java.net/jag/Image68-small.jpeg");
        addImage(cp, "http://today.java.net/jag/Image63-small.jpeg");
        addImage(cp, "http://today.java.net/jag/Image65-small.jpeg");
        addImage(cp, "http://today.java.net/jag/Image64-small.jpeg");
        JFrame f = new JFrame("Example");
        f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        f.setContentPane(cp);
        f.pack();
        //add a bit of space to show off centring
        f.setSize(f.getWidth()*6/5, f.getHeight()*6/5);
        f.setLocationRelativeTo(null);
        f.setVisible(true);
    static void addImage(JPanel cp, String url) throws MalformedURLException {
        JLabel label = new JLabel(new ImageIcon(new URL(url)));
        label.setBorder(BorderFactory.createLineBorder(Color.BLUE));
        cp.add(label);
}
