title: Save imagemagick file directly to s3 from ec2
body: <p>I download an image from a url to an ec2 instance(wget), process it with imagemagick (convert -actions $savedfilename) and then save it to s3 (with a php api).</p>
  
  <ol>
  <li>Is it possible to process the image on ec2 and save it directly to s3 without writing to the s3 volume?</li>
  <li>If this is possible, does it make sense - would it be faster / cheaper?</li>
  <li>Is there anything else that can be done to improve the efficiency of the process?</li>
  <li>Is there an API to save to s3 directly from the shell? </li>
  </ol>
