Set up a cheap CDN (MaxCDN is a good bet as someone else has mentioned) this website will help - http://www.cdncalc.com/ http://www.cdncalc.com/ this will half your monthly costs. I would stick with S3 for the origin to start with, setting up a bunch of servers to reliably store and serve data is a pain, and one you should avoid it if you can. On the CDN enable origin shielding, and set TTL of the images to never expire if you can. This will lead to images only to be served once from s3. When they upload, link to the CDN'd asset, it will pre-warm the CDN for subsequent requests. Without knowing the trends in your traffic, how much data you are storing etc, its hard to give you really good advice.
