Generate multi-resolution images for srcset with Grunt

I’m already a big fan of the Node based task manager Grunt for my day job; it makes minifying, and linting my code for errors a breeze. But this post by Google developer Addy Osmani caught me onto a new really cool Grunt task called grunt-responsive-images. It batch produces multiple, final resolution images for web deployment based on a list of original source images. Great for responsive web design and serving up basic HDPI imagery.
