How to use uploaded file acl?

[berkaytheunicorn]

I can't figured it out how can I keep uploaded files acl rules.

example:

If file uploaded with private/public-read, generated images should be private/public-read

I have no acl settings in my config and all generated files will have private acl.

I think you can do it with a couple of ways:

One is use fixed ACL setting in config.json. We have ACL configuration in all three of backup , reduce, and resize. See: https://github.com/ysugimoto/aws-lambda-image#configuration-parameters

The other is to get an original ACL from event object. But unfortunately putObject event won't pass image's ACL setting in event structure (https://docs.aws.amazon.com/AmazonS3/latest/dev/notification-content-structure.html). So if you want to do it, you need to write some additional code to get original ACL info by calling getObjectAcl before start to process this function (here).
