The flow should be as follows to watermark images whenever it is uploaded:

Raw image (without watermark) is uploaded to S3 bucket
Use S3 events (such as s3:ObjectCreated:* based on your need) to trigger Lambda. Hence, you need to configure S3 event destination as Lambda.
Lambda shall apply watermark and upload watermarked image

NOTE: If you don't use Lambda, other way is via SQS/SNS as event destination, and your worker shall take request from it and apply watermarking.
