"image/jpeg; charset=utf-8", which is not a valid MIMEType

I am trying to use an image with a "Web" source, the url points to an
aspx page on the same machine as the reporting server, this page
returns a jpeg image (a chart) created by some C# code. On the
"Layout" tab of VS.NET the image is displayed but when I switch to the
"Preview" tab I just get the dreaded Red X.
The following warnings are written to the Output window.
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.
The value of the MIMEType property for the image ?image1' is
"image/jpeg; charset=utf-8", which is not a valid MIMEType.
I have configured the UnattendedExecuionAccount (rsconfig -e...) and
the page which returns the image allows anonymous access but it
doesn't seem to make any difference. What I don't understand is the
message about the invalid MIMEType, the code which returns the image
sets the ContentType="image/jpeg".
Any help much appreciated.I began to get this error right after I installed "Office 2003 Pro".
Do you use MS Office 2003?
