Как мне загрузить картинку из корневой папки в стороне от проекта и вставить изображение в ASPXHTMLEDITOR

---

У меня есть
корневая папка="D://DigitalAsset/Photo/"
Initialfolder="Фото/"
У меня есть виртуальная папка в моем проекте с именем Images. поэтому я назначаю RootFolderUrlPath и UploadFolder следующим образом.
RootFolderUrlPath="~/Изображения"
UploadFolder="~/Изображения"

проблема в том, что когда я загружаю изображение с помощью селектора изображений, он загружает изображение в корневую папку, но не может загрузить изображение в вертикальную папку, которая является изображениями.Так что не могу быть вставлен в Редактор. Могу ли я получить решение для этого, пожалуйста.

Что я уже пробовал:

rootfolder="D://DigitalAsset/Photo/"
Initialfolder="Photo/"

RootFolderUrlPath="~/Images"
UploadFolder="~/Images"
