import javax.imageio.ImageIO;

public class Main extends Window {

  private BufferedImage pic;

  public static void main(String[] args) {
    GraphicsEnvironment ge = GraphicsEnvironment.getLocalGraphicsEnvironment();
    GraphicsDevice screen = ge.getDefaultScreenDevice();

    if (!screen.isFullScreenSupported()) {
      System.out.println("Full screen mode not supported");
      System.exit(1);
    }

    try {
      BufferedImage loadedpic = ImageIO.read(new File("your.jpg"));
      screen.setFullScreenWindow(new Main (loadedpic));
    } catch (Exception e) {
      System.err.println(e.getMessage());
    }
  }

  public Main (BufferedImage pic) {
    super(new Frame());

    this.pic = pic;

    addMouseListener(new MouseAdapter() {
      public void mouseClicked(MouseEvent e) {
        System.exit(0);
      }
    });
  }

  public void paint(Graphics g) {
    g.drawImage(pic, 0, 0, getWidth(), getHeight(), this);
  }
}

The code above generates the following result.
