The URLs of the images actually can be relative to the location of the CSS file that references them, there is no need for absolute paths. The Telerik.Web.UI.WebResource.axd handler is always requested from the root of the application, so the CSS files will be relative to the root and their images' URLs will be relative to their CSS files locations.
Unless I am missing something, relative URLs will suffice.
