    Default My image doesn't always appear on the screen?

    Hi guys I've been having this problem lately with an image I added to my panel. Whenever I compile and run my program the image sometimes appear on screen but most of the time it doesn't. I really don't know what's going on so I would really appreciate the help

    *The dimension of the image is 500x256

    import javax.swing.*;
    import java.awt.event.*;
    import java.awt.*;
     
    public class GameMainZombie {
     
    	public static void main(String[] args)	{
     
    	GameMainZombieGUI();
     
    	}
     
    	public static void GameMainZombieGUI() {
     
    	try	{
    	final JFrame pageMain = new JFrame("ZOMBIE GAME");
    	pageMain.setVisible(true);
    	pageMain.setSize(500,600);
    	pageMain.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
     
    	JPanel panel = new JPanel((LayoutManager) new GridBagLayout());
    	pageMain.getContentPane().add(panel, BorderLayout.CENTER);
    	GridBagConstraints c = new GridBagConstraints();
     
    	JButton Start = new JButton("START GAME");
    	Start.addActionListener(new ActionListener() { 
    		public void actionPerformed(ActionEvent e)	{
    		GameLocationGUI(); pageMain.setVisible(false);	}
    	});
    	c.gridx = 0;
    	c.gridy = 1;
    	c.insets = new Insets(10,10,10,10);
    	panel.add(Start, c);
     
    	ImageIcon image = new ImageIcon("Zombies.jpg");
    	JLabel main = new JLabel(image);
    	c.gridx = 0;
    	c.gridy = 0;
    	panel.add(main, c);
     
    	}catch(Exception e)	{}
     
    	}

    One possible problem is the call to setVisible() is done BEFORE everything is ready to be seen. Try moving the call to after everything is ready.

    Your label is getting on the screen. The issue is that it is not finding the file. I would google "load image with java" to see how to load an image file from your source code.
    Writing code is your job, helping you fix and understand it is mine.

    <-- Be sure to thank and REP (Star icon) those who have helped you. They appreciate it!

    the image sometimes appear on screen
    That sounds like a timing thing, not a location problem.
