Upload Resized Images

I am using the image resizer/cropper to make good versions of images I upload, but they won’t save (I believe because these new versions are not uploaded to the S3 server to replace the older ones). Is this something that can be implemented, or is there a workaround?

Also commented on it here: https://github.com/bradt/wp-tantan-s3/issues/27
