ImageCDN

This extension enables you to host category and product images on a separate server with ease. This can improve page load time by offloading some of the stress from your web server and by allowing you to utilize a high performance content delivery network (CDN) or another remote host. If your website has a large amount of traffic, using a CDN will help to bring down your bandwidth cost and speed up your response time. Currently, the extension integrates with Amazon S3, Coral CDN, Mosso/Rackspace Cloud Files, and any CDN, server or service that supports FTP, FTPS, or SFTP. Each adapter has a separate configuration menu with options unique to each. The abstract adapter can be extended to easily add support for any other CDN that has a published API. In this respect, we are always seeking new CDNs to include in this extension as well as community-provided implementations to be added.

The extension automatically distributes category and properly-sized product images to a CDN when they are referenced in the Magento templates. This code extends the functionality of category and product image getUrl() to determine the existence of the file on the CDN, push the image to the correct location if it isn't found, and return the CDN-specific URL. Installation of this extension into an operational store will work immediately as images already present will be uploaded to the CDN on demand. Because of this, you can install, enable, and disable this
