title: Saving an image for image recognition via REST on raspberryPi
body: <p>I am doing a project for image recognition. I want to send an image or a video from an android app to the raspberryPi, that is my server (I use flask), and make the recognition on the server and then send back the result to android. I want to do this with REST and python. So how can I do this? 
  I am new to all of this so any help is really helpful! </p>
