HTML email in Outlook - no background images?

[Morgan19]

I have a client who's dead-set on sending out their own HTML emails via Outlook. I create the HTML with absolute links for them via Dreamweaver; then they attach the HTML "as text" into a new Outlook message and send it out. It works surprisingly well except for one thing: Outlook always drops out any background image so that part of the message just looks blank.

Is there any easy way to force Outlook to display a background image correctly?
