Gif not showing up in JFrame

Question

I'm trying to get a gif to appear on one of my JFrame and the program compiles but doesn't show the gif I want it to show. Is it a matter of where I have the gif stored on my computer?

import javax.swing.*;
import java.awt.*;
import java.util.*;


public class iWorkoutScreen 
{  
  public void iWorkoutScreen()
  {      
    String calories = "this many";

    this.setBackground(Color.WHITE);
    this.setLayout(new BorderLayout()); 
    this.setPreferredSize(new Dimension(800, 400)); 
    this.pack();

    JButton button = new JButton("Press to Start Workout");
    this.add(button, BorderLayout.PAGE_START);

    JLabel timer = new JLabel("this timer will be better");
    timer.setPreferredSize(new Dimension(400, 10));
    ImageIcon timerIcon = new ImageIcon("7TaK4G8TA.gif");
    timer.setIcon(timerIcon);
    this.add(timer, BorderLayout.CENTER);

    button = new JButton("Button 3 (LINE_START)");
    this.add(button, BorderLayout.LINE_START);

    button = new JButton("Long-Named Button 4 (PAGE_END)");
    this.add(button, BorderLayout.LINE_END);

    JLabel caloriesBurned = new JLabel("You have burned " + calories + " calories!!");
    this.add(caloriesBurned, BorderLayout.PAGE_END);
  }
}

Problem is most likely location of the image. Please do a search. There are a number question asked here everyday regarding adding images, and many of the problems are caused by location of the file relative to the path being used.

Also you should be packing the frame _after_ adding your components — Paul Samsotha, Nov 07 '14 at 02:51
Application resources will become embedded resources by the time of deployment, so it is wise to start accessing them as if they were, right now. An [tag:embedded-resource] must be accessed by URL rather than file. See the [info. page for embedded resource](http://stackoverflow.com/tags/embedded-resource/info) for how to form the URL. — Andrew Thompson, Nov 07 '14 at 04:11

The following MCVE works. Not only does it change the method into a constructor, but also corrects other problems. It hot-links to an image so that it should work for anyone.

import java.awt.*;
import java.net.MalformedURLException;
import java.net.URL;
import javax.swing.*;

public class iWorkoutScreen extends JFrame {

    public iWorkoutScreen() throws MalformedURLException {
        String calories = "this many";

        this.setBackground(Color.WHITE);
        this.setLayout(new BorderLayout());

        JButton button = new JButton("Press to Start Workout");
        this.add(button, BorderLayout.PAGE_START);

        JLabel timer = new JLabel("this timer will be better");
        ImageIcon timerIcon = new ImageIcon(
                new URL("http://i.imgur.com/T8x0I29.png"));
        timer.setIcon(timerIcon);
        this.add(timer, BorderLayout.CENTER);

        button = new JButton("Button 3 (LINE_START)");
        this.add(button, BorderLayout.LINE_START);

        button = new JButton("Long-Named Button 4 (PAGE_END)");
        this.add(button, BorderLayout.LINE_END);

        JLabel caloriesBurned = new JLabel(
                "You have burned " + calories + " calories!!");
        this.add(caloriesBurned, BorderLayout.PAGE_END);
        this.pack();
    }

    public static void main(String[] args) {
        Runnable r = new Runnable() {

            @Override
            public void run() {
                try {
                    JFrame f = new iWorkoutScreen();
                    f.setLocationByPlatform(true);
                    f.setVisible(true);
                } catch (MalformedURLException ex) {
                    ex.printStackTrace();
                }
            }
        };
        SwingUtilities.invokeLater(r);
    }
}
