PROBLEM
Images, Charts, Barcodes and Shapes are not being displayed in the Silverlight report viewer.

DESCRIPTION
When a report is previewed in the Silverlight report viewer, Images, Charts, Barcodes and Shapes are missing, however they are present when exporting to one of the supported formats.

SOLUTION
The most probable reason is missing resource endpoint for the Telerik Reporting WCF Service that is responsible for serving all images: Picturebox, Chart, Shapes and Barcodes. For proper configuration please refer to the Hosting WCF Service in IIS help article.
The Silverlight report viewer lives entirely on the client side, while the report rendering is performed on the server. The XAML rendering extension (used by Silverlight report viewer) streams images as resources (similar to HTML), so if the resource endpoint is missing in the service configuration, the images would not be served. When exporting, images are embedded in the export file.
