Add Image to JOptionPane

Question

I'm wondering How To Add Image To MessageDialog Box. I tried the code below and the image was nowhere to be found

else if(button == B){
String text = "blahblahblahblahblah";
    JTextArea textArea = new JTextArea(text);

textArea.setColumns(30);
textArea.setLineWrap( true );
textArea.setWrapStyleWord( true );
textArea.setSize(textArea.getPreferredSize().width, 1);
Font font = new Font("Verdana", Font.BOLD, 12);
textArea.setFont(font);
textArea.setForeground(Color.BLUE);
JOptionPane.showMessageDialog(
null, textArea, "Border States", JOptionPane.PLAIN_MESSAGE);

image2 = new ImageIcon(getClass().getResource("borderstates.jpg"));
  label2 = new JLabel(image2);
  add(label2);

JOptionPane is a very flexible API.

Your first port of call should be the Java API Docs and the Java Trails, specific How to use Dialogs

public class TestOptionPane04 {

    public static void main(String[] args) {
        EventQueue.invokeLater(new Runnable() {
            @Override
            public void run() {
                try {
                    UIManager.setLookAndFeel(UIManager.getSystemLookAndFeelClassName());
                } catch (ClassNotFoundException | InstantiationException | IllegalAccessException | UnsupportedLookAndFeelException ex) {
                }

                ImageIcon icon = new ImageIcon(TestOptionPane04.class.getResource("/earth.png"));
                JOptionPane.showMessageDialog(
                        null,
                        "Hello world",
                        "Hello", JOptionPane.INFORMATION_MESSAGE,
                        icon);
                JOptionPane.showMessageDialog(
                        null,
                        new JLabel("Hello world", icon, JLabel.LEFT),
                        "Hello", JOptionPane.INFORMATION_MESSAGE);

            }
        });
    }
}

What is a MessageDialogBox? If you mean add an image to a JOptionPane, there are method overloads that accept an Icon, and so this is one way to solve this. Another is to create a JPanel or JLabel with your image and other components and then display this in the JOptionPane.
