Load Image from Documents Directory EasyAR

I want to load Image dynamically. So after fetching the image from Server, I'm saving it in Documents Directory. How to load that image in ImageTarget.

Storage Types: https://www.easyar.com/doc/EasyAR%20SDK/Unity%20Plugin%20Reference/2.0/StorageType.html?highlight=storagetype

Is there any other way to handle this?
