sql server reporting services: I am serving up reports using the web service using the render method.
The reports have images on them. The following scenarios work

..Net application and Reporting Services are all on the same
workstation. Images show up and everything works well.

..Net application on same workstation and I point to Reporting Services
which is on Test environment server A. Images show up and everthing
works well.

This is not working

..Net application is on server B and Reporting Services is on the same
server A. The report shows up but all images show up with the red x.

What can be different between the code on my local workstation and the
code on the server? I have copied all the neccessary files out there.
Is there something on my workstation which has Visual Studio installed
that is not on the server B which only has IIS installed? Or is there
something else I could be missing in the migration to the server
environment?

We have found that the report comes up just fine in the server
environment but the image is using different credentials than the user
that is logged in. If we run impersonate as user ABC, all reports come
up fine under ABC, but the image prompts a login box. The image wants
to load under the users that logged in and not the user we use to
impersonate. Any thoughts on how to get around this?
