Retrieves the URL of the images directory.
Multiple content servers can share user interface images from one Content Server installation. This variable defines the URL path to the DomainHome/ucm/cs/weblayout/images directory of the content server whose image files are being shared.
Returns the relative URL as a string. If the URL is external, the complete URL is returned rather than the relative path.
Returned for a Content Server:
HttpImagesRoot=/domain/images/
