PNG image returning null

Question

I can't for the life of me figure out what is wrong with the following code:
import java.awt.Color;
import java.awt.Dimension;
import java.awt.Graphics;
import java.awt.image.BufferedImage;
import java.io.File;
import java.io.IOException;
import javax.imageio.ImageIO;
import javax.swing.JFrame;
import javax.swing.JPanel;
public class CTFMain extends JPanel
    BufferedImage tileset;
    CTFMain()
        super();
        int width = 400;
     int height = 400;
     setPreferredSize(new Dimension(width, height));
        try
            //tileset = Toolkit.getDefaultToolkit().createImage("images\\EnvironmentTile.png");
            tileset = ImageIO.read(new File("images\\EnvironmentTile.png"));
        catch(IOException e)
    public void tic()
        repaint();
        System.out.println(tileset.toString());
    @Override
    public void paintComponent(Graphics g)
        g.setColor(Color.white);
        g.fillRect(0, 0, getWidth(), getHeight());
        g.setColor(Color.red);
        g.fill3DRect(20, 30, 150, 350, true);
        if(tileset == null)
            System.out.println("it's null");
        else
            g.drawImage(tileset, 0, 0, this);
    public static void main(String[] args)
        JFrame frame = new JFrame("Capture the Flag");
        CTFMain game = new CTFMain();
        frame.add(game);
        frame.pack();
        frame.setResizable(true);
        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        frame.setVisible(true);
        while(true)
            game.tic();
            try
                Thread.sleep(1000/33);
            catch(Exception e)
}Whenever I run the program, tileset gets assigned a null value, even though the path file is there, so when it calls drawImage, it draws a blank picture. What am I doing wrong?
Note: The println and fill3DRect statements are there to test if those methods are working, and they are.

Yes, I need the information.
.. Because I don't know how to do that...Then it looks like you are stuffed, unless you can either do some research into the 'Java SDK Jar tool' and/or ask a smart question.
