There is no concept of a "background image" in a JPanel, so one would have to write their own way to implement such a feature.

One way to achieve this would be to override the paintComponent method to draw a background image on each time the JPanel is refreshed.

For example, one would subclass a JPanel, and add a field to hold the background image, and override the paintComponent method:

public class JPanelWithBackground extends JPanel {

  private Image backgroundImage;

  // Some code to initialize the background image.
  // Here, we use the constructor to load the image. This
  // can vary depending on the use case of the panel.
  public JPanelWithBackground(String fileName) throws IOException {
    backgroundImage = File(fileName));

  public void paintComponent(Graphics g) {

    // Draw the background image.
    g.drawImage(backgroundImage, 0, 0, this);

(Above code has not been tested.)

The following code could be used to add the JPanelWithBackground into a JFrame:

JFrame f = new JFrame();
f.getContentPane().add(new JPanelWithBackground("sample.jpeg"));

In this example, the method was used to read in the external JPEG file.

Here is another quick approach without using additional panel.

JFrame f = new JFrame("stackoverflow") { 
  private Image backgroundImage = File("background.jpg"));
  public void paint( Graphics g ) { 
    g.drawImage(backgroundImage, 0, 0, null);

This is easily done by replacing the frame's content pane with a JPanel which draws your image:

try {
    final Image backgroundImage = File(...));
    setContentPane(new JPanel(new BorderLayout()) {
        @Override public void paintComponent(Graphics g) {
            g.drawImage(backgroundImage, 0, 0, null);
} catch (IOException e) {
    throw new RuntimeException(e);

This example also sets the panel's layout to BorderLayout to match the default content pane layout.

(If you have any trouble seeing the image, you might need to call setOpaque(false) on some other components so that you can see through to the background.)
