Would it be possible to use some tag in the html so that MailScanner
could evaluate/find to not duplicate if found?  Maybe use the alt=
text to determine if the image and the alt= text already exists?  Or
if there is an accurate method to detect a reply or forward from the
headers and have a MailScanner.conf option or rule to only include it
on original emails and not reply or forwards similar to how most email
clients work.
