The essence of the question in the header.
Googled, poked the docks but never found. All I could get, this is an example where working with the file download. Tried to change, failed. Please tell me. So I launched, worked with the picture, and I want to take input from url new pictures, let it even on the server with the app is that would not CROSS to do, and I want the new picture to cropp for processing in place of the old, and all is well in width and height lined up.
