Content-Type of GIF

Dear Clement,

my problem with the extra CR/LF in a GIF file was indeed due to the
inappropriate automatic generation of the tsource in my request.

When I requested the image without any command keyword, just the URL,
I received the correct image data. But now there's another problem.
The attachment starts with the following lines:

Content-Type: application/binary; name="winner_mitmach.gif"
Content-Transfer-Encoding: base64
Content-Disposition: attachment; filename="winner_mitmach.gif"
Content-Description:  GIF image data, version 89a, 460 x 57,

Although the Content-Description tells that it's a GIF image, this isn't
the case with the Content-Type. The "application/binary" causes my
browser to not display the image, as it should, but to ask me as what
file I wished to save it. How comes that the Content-Type isn't right?

Best regards
Dietmar
