This is my presentation deck from CASCADE BOS meet up @Bocoup on September 22, 2015
You can view it here: http://daigofuji.github.io/responsive-images/#1
This repo also serves as a place for grunt-responsive-image. For more info see linkes from towards the end of my slidedeck.
Put your images in img-src
folder, run npm install
then grunt
Your processed image should appear inside /dist
Good luck!
