Note: The default Heroku instructions for S3 uploads are incorrect. You need to specify your exact region, and setup a Bucket Policy:

{
	"Version": "2008-10-17",
	"Statement": [
		{
			"Sid": "AllowFileUpload",
			"Effect": "Allow",
			"Principal": {
				"AWS": "arn:aws:iam::XXXXXXXX:user/instaswan"
			},
			"Action": [
				"s3:PutObject",
				"s3:PutObjectAcl"
			],
			"Resource": [
				"arn:aws:s3:::instaswan-dev",
				"arn:aws:s3:::instaswan-dev/*"
			]
		}
