pricing compared to s3: assuming 5,000 photos ~5gb of data. $0.15 for storage 40gb of outgoing traffic is $4.80 So you're basically paying double the s3 prices for convenience. This service also does image manipulation and cdn integration. So you should also calculate your expected cost of using ec2 and a cdn. (BTW not ripping on the op. I like the service and was genuinely calculating the costs for my own use case).
