With some changes, the JPanel resize to the image size:
import javax.swing.*;
import java.awt.*;
import java.net.URL;
/ A <code>JFrame</code> with a background image */
public class BackgroundImage extends JFrame
     final ImageIcon icon;
     final boolean isRedimensionable;
     public BackgroundImage(URL url, boolean isRedimensionable) {
          icon = new ImageIcon(url.getFile());
          this.isRedimensionable = isRedimensionable;
          JPanel panel = new JPanel()
               protected void paintComponent(Graphics g)
                    if (BackgroundImage.this.isRedimensionable) {
                         //  Scale image to size of component
                         Dimension d = getSize();
                         g.drawImage(icon.getImage(), 0, 0, d.width, d.height, null);
                    } else  {
                         //  Dispaly image at at full size
                         g.drawImage(icon.getImage(), 0, 0, null);
                    super.paintComponent(g);
          panel.setOpaque( false );
          getContentPane().add( panel );
          Dimension dim = new Dimension(icon.getIconWidth()  +getInsets().left+  getInsets().right, icon.getIconHeight()  +getInsets().top+  getInsets().bottom) ;
          panel.setPreferredSize(dim);
          setResizable(isRedimensionable);
          pack();
          JButton button = new JButton( "Hello" );
          panel.add( button );
     public static void main(String [] args)
          BackgroundImage frame = new BackgroundImage(BackgroundImage.class.getResource("loginDialogBackground.png"), true);
          frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
          frame.setLocationRelativeTo( null );
          frame.setVisible(true);
}
