From the article, here's a good excerpt of what Chute does. [Chute] handles the entire backend environment for uploading, processing, authenticating, resizing, and serving images. ...for example, you’re running a popular website and you want all of your users to be able to have profile images, you can sign up for Chute and paste a few lines of code into your application, and that’s it. Users will then be able to upload images to Chute’s servers, where they will be cropped, resized, etc. according to your specifications, before being served onto your site. That's pretty useful!
