Как отобразить изображение на странице редактирования в бэкэнде в Magento 2?

Я создал пользовательскую сетку в серверной части magento 2, пользователь может вставлять значения из серверной части и внешнего интерфейса. Я также загрузил изображения в базу данных. Теперь мой запрос заключается в том, что я хочу отобразить изображение на странице редактирования.

Save.php

             if(isset($_FILES['photo']['name']) && $_FILES['photo']['name'] != '') {
