Libpixel

Libpixel works by giving you the power and flexibility of responsive images without having to build the complex infrastructure required to support them. Delivering the optimal version of an image for a given device has a significant impact on how fast your website or app loads and therefore how your users perceive you. You simply supply the image size or processing you want in the query string in the URL you use for the image (perhaps in an IMG tag), and LibPixel does the rest.
