We have DNN 4.5.3 running on a W2K3x64 and attempting to use the Reporting Service Visualizer.  We've developed a report in Business Intelligence Development Studio which builds completely.  We have loaded an instance of the Report Module 4.5.2.  We're unfamiliar with the Module's Report Setting.  These are the present settings  

Visualizer = Expermential Reporting Service Visualizer

Height = 200

Local Report - selected

Data Source Name= the dataset used in the report

Report Files = Directory and Files name of a copy of the report loaded with file manager from the BIDS project folder.

The report does not render and an error message appears

  • Report 'SalesInvoices' contains external images. The EnableExternalImages property has not been set for this report.

 How do we set this property?

Additionally there is an exception in the Event Viewer which reports

At this point, the Reporting Service Visualizer is an Experimental Beta release and does not support many of the features of the ReportViewer control. Specifically, it does not support the EnableExternalImages property, so you will have to dig into the code to change it. If you look at the ~/DesktopModules/Reports/Visualizers/Reporting Services/Visualizer.ascx.vb file, and have a little VB.net knowledge, it should be straightforward to set this property to the value you need. In the mean time, I have logged an Enhancement request (RPT-5806) so this will be looked at for the final version of that Visualizer.

I don't have access to the source code at the time of writing this so I can't give an exact workaround, but I'll take a look as soon as I have a chance and try to post something here.

The exception you are looking at seems to be unrelated to the Reports module itself, as it comes from a Core component. Everything outside of the "Report Settings" section of the Settings page for the Reports module is provided by the Core. You may find a better answer by posting that in one of the Core forums.
