I'm a fan of pilbox [1]. It's "fast" (builds off of OpenCV + Tornado), easy to understand and does much more than just image resizing. Also, it should be simpler to deploy than OpenRoss - since it doesn't bake in nginx, you can deploy it to Heroku (which is what we do), or behind Amazon's ELB. We use it on a fairly large production site, and it works fine. If you throw it behind CloudFront or some other CDN that supports cache busting, it's plenty fast. 1: https://github.com/agschwender/pilbox https://github.com/agschwender/pilbox
