Question

Drupal 7 I need to replace images in files system and also replace over S3 bucket without changing url of image over S3.

I am using s3fs module for upload images over S3.

       "Action":"s3:PutObject",
       "Resource":"arn:aws:s3:::examplebucket/*"
     },
     {
       "Sid":"112",
       "Effect":"Deny",
       "Principal":{"AWS":"1111111111" },
       "Action":"s3:PutObject",
