You can set a bucket policy as detailed in this blog post:
http://ariejan.net/2010/12/24/public-readable-amazon-s3-bucket-policy/
As per @robbyt's suggestion, create a bucket policy with the following JSON:
{ "Version": "2008-10-17", "Statement": [{ "Sid": "AllowPublicRead", "Effect": "Allow", "Principal": { "AWS": "*" }, "Action": ["s3:GetObject"], "Resource": ["arn:aws:s3:::bucket/*" ] }] }
Important: replace bucket
in the Resource
line with the name of your bucket.
