Help - 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.Make sure you are using RS SP1

I have SP1 installed (did it again to make sure!). The problem does
not occur when displaying external images that come from a file, but
only when they are returned from code (in an aspx.cs module). I am
beginning to think it could be some kind of security/permission
problem, but I don't know where to look for more info on this. for
example the following url will work
http://10.34.3.76/Trending/myImage.jpg
but this one doesn't
http://10.34.3.76/Trending/getImage.aspx
Any ideas ?

IUSR and IWAM too).

chart via an aspx web page to perform advanced charting that RS charting can
not do. If I can not get this to work, I do not know how I will be able to
generate the charts that I need within the report. Just as Mark gets, I get
the MIME type error in the preview, a red X when viewed through RS, but the
designer show the image. I have setup Unattended Execution and that made a
slight difference in that the image dimensions were set, but no image.
Please help, I am at wits end.

Do you use MS Office 2003?

show up in the designer but not the preview or the full report (with
SP1)
I noticed the error said the invalid mime type was "image/jpeg;
charset=utf-8" or similar
So on the aspx file that returned the jpeg, right below
response.contenttype="image/jpeg"
I added:
response.charset=""
and now the images appear on the report! Looks like reporting services
isn't parsing the HTTP headers correctly...
