I'd call using Word to generate HTML lots of things but ambitious isn't one of them.
Also, if you send me an email then HTML is disabled by default so no remote images will show (until I allow it - some sender's emails I've got to display them, others are set not to. I like the fact that I can pick and choose some senders rather than have a blanket "on/off" policy). Only the text will show if images aren't allowed.
With gmail, I get "enable images once" or "enable always" and in emails where images are already enabled,
"Images from this sender are always displayed, Do not display from now on."
