Most leading blogs deliver their assets (images, JS, CSS, etc.) through state-of-the-art CDNs and utilize online resizing technologies. With faster, off-site access, they greatly improve their users’ browsing experience, while reducing load on their servers.
Using Cloudinary you can use these same technologies today, in your website or blog, without any hassle. Simply direct all your media assets to Cloudinary and they would be delivered to your visitors through Amazon’s powerful CDN network. You can even add alternative dimensions to your images’ URL and get your pictures in any desired size or perspective. All of this with minimum changes on your side.
UPDATE - March 2013

How it’s done? Simply prefix all your images with:
https://res.cloudinary.com/<your cloudinary cloud name>/image/fetch/
Here's a quick example:
Both URLs return the exact same image, only the second one is cached and delivered through fast, localized CDNs and not via your local web server. Better experience to your users. Lower load on your server. Lower hosting costs.
You can use this method to create different sized thumbnails for the same photo. For example, creating a 150x150 crop focused on Jennifer’s face ('g_face') and with rounded corners of 20 pixels ('r_20') generates the following beautiful image:
If you are a developer, you can do the same from code. For example, in Ruby on Rails:
:type => :fetch, :width => 150, :height => 150,
:crop => :thumb, :gravity => :face, :radius => 20)
Note that if the image behind the original URL changes, Cloudinary will automatically update the images and videos embedded in your site and all its resized versions.
To summarize, any blogger and any website owner can now optimize and deliver images faster through a CDN for images and seamlessly create smartly resized and cropped images in any dimension. All that by just adding the Cloudinary resource URL as a prefix to all images and videos.
