如何顯示從 django 管理員上傳到 heroku 的圖像？

Question

我在 heroku 上部署了我的 django 項目。 除了一些圖像損壞之外，該網站一切正常。 這些圖片都是我通過 django 管理員上傳到我在本地服務器上的網站的圖片。 這些圖像通過在 django 管理頁面的圖像字段中提供 url 上傳到我在本地服務器上的站點。 顯示在 html 代碼中硬編碼並且是我項目中的靜態/圖像文件夾的所有圖像。 我應該對我的 settings.py 文件進行任何更改以顯示這些圖片嗎？ 如何解決這個問題？

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

注意這個 src="{{product.imageURL}}。這就是我將圖片上傳到此購物車的方式。
