Anyway if you want to process thumbnails using an EC2 instance, you can setup your own processing server using imgr or thumbd.
If you think setting up & maintaining a server purely for image processing is too much of a hassle, I suggest using external services like Blitline or thumbr.it. I've got a demo of Rails + Blitline working if you're interested.
Manners man.
