Can't see inline image with Microsoft Outlook.

Hi,

I am sending html message having embedded image in it, When I receive
it using Outlook Express it shows me message properly with image, but
if I use MS Outlook then I can't see image

I am adding image as Inline in message. Here is my header for same:

Content-Type: application/octet-stream; name=ms_logo.gif
Content-Transfer-Encoding: base64
Content-Disposition: inline; filename=ms_logo.gif
Content-ID: ms_logo.gif

Am I doing anything wrong? I have tried by removing Content-Disposition
header. But no use

Any help would be greatly appreciated.

Thanks,
Shilpa
