body: <p>I can't find a way to implement a profile pic saving, can somebody help me with example?
  I'm capturing an image using MediaPicker (from Xamarin Labs), and then don't know how to crop it or resize to smaller mb size, tried Xamarin Resizer, but can't crop image if it is in wrong format.</p>
