manage/store images files of your website in the cloud

The advantages of using Cloudinary is so big that it was an easy decision to integrate it. Images are seamlessly delivered through Akamai’s fast CDN. By not bogging down GitHub with large images you are also being a good netizen.
Cloudinary is a cloud service that offers a solution to a web application’s entire image management pipeline. Easily upload images to the cloud. Automatically perform smart image resizing, cropping and conversion without installing any complex software. Integrate Facebook or Twitter profile image extraction in a snap, in any dimension and style to match your website’s graphics requirements.
When you upload your image to your article in the PageDown editor it will be sent to your Cloudinary account where you can use the web interface to interactively manage your media library.
