compatibility HTML email Outlook 2003 with other email-programs

[marten visser]

I try to make a HTML email-stationary with Outlook 2003. I use the same
template as with Outlook 2000. But I used the CSS-style:
background=no-repeat. Outlook 2003 doesn't recognize that so I have to change
that. So I made a table with in the upper TD a background-image. But now
Outlook 2003 sends that image as attachment to other email programs. In fact;
even the standard Oulook 2003 stationaries are being send as attachment to
other email programs. Even non-background-images like stationary Sunflower.
How in the world can we set up the HTML for a stationary WITHOUT attachments
being send to any other email-programs? It worked in Outlook 2000 so what has
changed????? The world isn't limited to Outlook 2003. Please respond.
