Add a new image property: "ExternalUrl" ExternalUrl property allows the user to input an ExternalUrl, when the application is in development mode it would load the local image files, when the application is deployed on a production server and the "ExternalUrl" has been set the eSpace application will load the image from the ExternalUrl.
This is good when you have your images hosted externally, or your media resources files are hosted on a CDN (akamai, limelight, etc).
Why would you bother to host your media/image files externally? to reduce http server request, and reduce your web server load. Improve user experience.
(useful for big web applications).
