Displaying images that are accessed through URL

Hi,

I have trouble displaying images that are accessed through URLs in my report.
If I call the URL directly in the Browser the Image can be opened without problems.
The images can be accessed with an anonymous access.

When I deploy the report or in the Preview of Visual Studio I get the following message:

[rsWarningFetchingExternalImages] Images with external URL references will not display if the report is published to a report server without an UnattendedExecutionAccount or the target image(s) are not enabled for anonymous access.

In Layout View of Visual Studio the image is showen correctly.

The Images are stored on a Solaris maschine with WebSphere 6.0 as WebServer.

Any ideas?

Thank you.

Frank
