仅允许在 AWS S3 中公开访问图像

Question

I'm new to AWS and it make me confuse, it's hard to use. I have a web app, which use images from folder /images/ in bucket. I have other /mp4/ folder which save videos.

Now I want public access to images folder only. How do I write the permission policy? I dont want people access my mp4 files by entering url.

Thank you for help

This policy will allow public access to objects from the images/ folder in the my-bucket bucket:

{
  "Version":"2012-10-17",
  "Statement":[
    {
      "Effect":"Allow",
      "Principal": "*",
      "Action": "s3:GetObject",
      "Resource": [
        "arn:aws:s3:::my-bucket/images/*", 
        "arn:aws:s3:::my-bucket/other-folder/* "
      ]
    }
  ]
}

Before adding this policy, turn off S3 Block Public Access for the bucket (turn off the two options that mention Bucket Policy).
