title: What is best way to upload images from mobile (iOS or Android) to server
body: <p>I want to send a picture from my mobile to my server, and i know how to send it using <strong>base64</strong> but i've heard that base64 is not recommended to use because base64 encoding increases the size of image by 37%, which in case slows down the performance of server because there will be too many images shared by users on the server. </p>
  
  <p>can anyone recommend me the efficient technique than base64 encoding for the mobile based image sharing application <code>(client-server app)</code>? </p>
