title: Most efficient way to send image to frontend
body: <p>I have images stored in Google Cloud Storage. Whenever my frontend (Swift) requests a certain image I would like to send the image as quickly and efficiently as possible from my backend.</p>
  
  <p>Conveniently, Google Cloud Storage has direct image links for every image.</p>
  
  <p><strong>Is it most efficient to send a multipart/form-data the same way I send an image captured by a user in the front end to the backend? Or is it more efficient to send the URL of the image stored in the cloud where the frontend can proceed to download the image from that URL?</strong></p>
