   Can anyone point me in the right direction for configuring
   Gnus to display images in HTML mail?

   [...]

   I have yet to find the relevant configuration for this so I
   thought I would ask and see if anyone knew.

Before you asked i did not know, but i know how to find out:

 M-x apropos RET gnus-.*image RET

If you do this and post your findings, then together we will
have answered this question in the most fulfilling way, IMHO.
