How can we save an image chosen by the user to google drive using app inventor?

I'm trying to save an image chosen by the user to google drive using app inventor. How do i do so?

--

see my example here https://puravidaapps.com/drive.php

Its not clear.. Could u pls explain the php  part more clearly? Also is there any way i can save it to drive directly without using php?

that example does not use php, it uses only App Inventor

you might want to read the large green box on the bottom of that page
