Status Code 200 is normal? or 304 is normal? Images are public and fixed so 365 days same images will be provided for every users.

I set Cache-Control as max-age=31536000 on Amazon S3 when I upload images.

Please help. :) Can you check how to set up correctly?

I want to save money for bandwidth.

Status codes 200 in 304 are both OK. All errors are in the 400 range.

200 meansOK.
304 means Not Modified: the cached content can be reused by the client. If you get a 304 caching works.

Check https://en.wikipedia.org/wiki/List_of_HTTP_status_codes for more details.
