如何显示从 django 管理员上传到 heroku 的图像？

Question

I deployed my django project on heroku. The site is all working well except for the fact that some images are broken. These images are all images which I uploaded to my site in local server via the django admin. These images were uploaded to my site on local server by providing the url in image field in django admin page. All the images which are hard coded in the html code and are static/images folder in my project are displayed. Any changes I should make to my settings.py file to dipslay these pictures? How to resolve this?

            </div>
        {% endfor %}
    </div>
{% endblock content %}

notice this src="{{product.imageURL}}. This is how I uploaded pictures to this cart.
