title: S3 - uploading with the same name?
body: <p>I'm uploading images to S3 using their API and putObject.</p>
  
  <p>When I upload an image which has the same key as an object already in the bucket, the original object is overwritten.</p>
  
  <p>Is there away around this?</p>
  
  <p>I've checked <a href="https://stackoverflow.com/questions/12654828/amazon-s3-avoid-overwriting-objects-with-the-same-name">SO</a> but it's quite an old question now, are there any newer/better methods?</p>
