Without creating a Cloudwatch Event, it is possible on S3 to directly associate a lambda function as soon as a new object is created. The lambda function will get the path, read the object, resize the image and save again with a different name (or different folder). I'll definetely go with D

A developer can configure AWS Lambda to directly process each S3 event for each S3 object upload. AWS Lambda can be triggered by S3 events and can execute code that can resize the uploaded photo to a thumbnail and upload the thumbnail with a new name to the same S3 bucket.

S3 sends notification to lambda (asynchronous invocation), creates the thumbnails, and uploads back to S3
