I   copied&pasted   this   code   from   an   existing   unit   I   have,   and   it   should   do   exactly   what   you   want.   The   trick   however   isn't   just   adding   the   image(s)   as   attachment   but   also   telling   OE   or   Outlook   where   to   find   them.   To   do   this,   use   the   "cid:imagename.jpg"   tag   in   your   HTML   code   for   the   images.   Also,   use   the   ExtraHeader   property   to   set   'Content-ID'   to   the   name   of   the   image   as   it   appears   in   your   cid:   tag.   Thus,   if   you   use:

then   you   add   this   header:
      Attachment.ExtraHeaders.Values['Content-ID']   :=   ' ';
Now,   the   image   MUST   still   be   added   as   an   attachment   since   pure   HTML   cannot   handle   inline   images.   But   if   you   use   this   technique   then   whomever   reads   this   email   will   see   a   background   image   and   a   second   image   as   part   of   the   email,   exactly   like   you   wanted   it   to   appear.   (If   their   browser   can   display   HTML   emails.   Otherwise   they   see   plain   text.)   The   _attached_   will   be   embedded   in   your   email   this   way.
Here's   the   (stripped)   code   example.   I   hope   it   still   works.   :D
procedure   TFormMain.SendMail(Recipient,   Address:   string);
const
      sStars   =   'BackgroundStars.jpg';
