You can use bucket policies in your Amazon bucket to allow your application's domain to access the file. In fact, you can even add your local dev domain (ex: mylocaldomain.local) to the access list and you will be able to get your images. Amazon provides sample bucket policies here: http://docs.aws.amazon.com/AmazonS3/latest/dev/AccessPolicyLanguage_UseCases_s3_a.html. This was very helpful to help me serve my images.

The policy below solved the problem that brought me to this SO topic:

       "Version":"2008-10-17",
       "Id":"http referer policy example",
       "Statement":[
    {
      "Sid":"Allow get requests originated from www.example.com and example.com",
      "Effect":"Allow",
      "Principal":"*",
      "Action":"s3:GetObject",
      "Resource":"arn:aws:s3:::examplebucket/*",
      "Condition":{
        "StringLike":{
          "aws:Referer":[
            "http://www.example.com/*",
            "http://example.com/*"
          ]
        }
      }
    }
  ]
