Apache poi java: Image not showing in document when running JAR file in another computer

I created an app that works with files and works perfectly in the computer where I wrote the code, however it does not work correctly in other computers. After reviewing the entire code I was able to find the issue. I removed the following method that adds an image and the jar file works fine in multiple computers, however I need the image to be added. The method is the following: (doc is a static variable declared in another class, in case you wonder)

            public void AddImage() throws IOException, InvalidFormatException {

        XWPFParagraph parag = document.createParagraph();
        XWPFRun r = parag.createRun();

        URL imageURL = ClassLoader.getSystemResource("TheImage.png");
        String imageName = imageURL.getPath();
        File image = new File(imageName);
        FileInputStream fis = new FileInputStream(image);

        BufferedImage bimg1 = ImageIO.read(image);
        int width = 160;//bimg1.getWidth();
        int height = 26;//bimg1.getHeight();  

        String imgFile = image.getName(); 

        r.addPicture(fis, document.PICTURE_TYPE_PNG, imgFile, Units.toEMU(width), Units.toEMU(height));
    }

To give you more details, I created a source file in the project in eclipse where I added the image, does anybody know how to solve this?

Perhaps on your computer the image is taken from the file system instead from the jar. Is the image packaged in the jar file? Then try 

Inputstream logo = getClass().getResourceAsStream("/path/in/jar/img.png");

to load it.
