(Note that X-Face and Face are two different syntaxes; both declare a
48x48 graphic, but X-Face has a custom format for a black-and-white
bitmap, Face is a base64-encoded color PNG file.)

I might do something like

(setq hq-face (gnus-face-from-file "~/.xfaces/face.jpeg"))
(setq gnus-posting-styles (("^gnu\\.emacs\\.gnus$" (face hq-face))))

Or, alternatively

(setq hq-face-file-name (expand-file-name "~/.xfaces/face.jpeg))
(setq gnus-posting-styles
  '(("^gnu\\.emacs\\.gnus$"
     (face (lambda () (gnus-face-from-file hq-face-file-name))))))

The first form should be more efficient in only building the face string
once (at load time); the second form will work if you change the file
name variable or contents of the file while Gnus is running.  You could
also inline it into the posting styles variable itself.

info://gnus/Posting+Styles is pretty informative and has an extended
example you could probably work from.
