title: Rotate Image in Amazon S3
body: <p>I have a bunch of images in Amazon S3 that I need to physically rotate. I currently do this by downloading the image to my server, rotating it using GD and overwriting it back to S3.</p>
  
  <p>This process takes ~5 secs per image. I was wondering if there is any AWS API or such that can do this rotation directly in S3, preferably as in a batch mode?</p>
  
  <p>I would appreciate it if anyone who has any experience with that kind of stuff can give me any pointers!</p>
