Optimizing Fast Image Delivery

I am using Sencha.io Src to deliver the homepage banner and screenshots for my sites and motion. Sencha.io Src is a free service that optimizes images and delivers them according to user’s device. Sencha.io Src is a perfect complement to responsive web design. The implementation is very simple. All you have to do is attaching this url (http://src.sencha.io/) in front of your image source.
