dired-x.el says:


;;; * Parse `dired-guess-shell-alist-user' and
;;;   `dired-guess-shell-alist-default' (in that order) for the first REGEXP
;;;   that matches the first file in the file list.
;;;
;;; * If the REGEXP matches all the entries of the file list then evaluate
;;;   COMMAND, which is either a string or a Lisp expression returning a
;;;   string.  COMMAND may be a list of commands.


What are dired-guess-shell-alist-user and dired-guess-shell-alist-default set
to?  If they have an entry like

        ("\\.\\(gif\\|jpg\\)\\'" . "xloadimage")

instead of (or in front of) 2 separate entries for GIF and JPEG files, then it
should work the way you want.
