Instead of using /./resources/back_img.png, use resources/back_img.png with ClassLoader.
Here is example :

    String path = "resources/back_img.png";
    ClassLoader cl = ImageHandler.class.getClassLoader();
    URL imgURL = cl.getResource(path);
    //URL imgURL = ImageHandler.class.getResource(path);

    if (imgURL != null) {
        ImageIcon icon = new ImageIcon(imgURL, description);
        Image img = icon.getImage();
        Image sizedImg = img.getScaledInstance(width, height, Image.SCALE_DEFAULT);
        return new ImageIcon(sizedImg);
    } else {
        System.err.println("Couldn't find file: " + path);
        return null;
    }
