The preview-images are displayed as overlays containing a link to
the image-files in there properties.
Here is a rough sketch :

(defun tex-open-preview-at-point ()
  (interactive)
  (let ((ov (car (overlays-at (point))))
        (file (plist-get (cdr (overlay-get ov 'display))
                         :file)))
    (unless file
      (error "No preview here"))
    (start-process "display" nil "display" file)))

 
It is some more work, to display the actual image, provided there is one
(like in \includegraphics etc.).  AFAICS preview-latex does not
determine this.

But using the overlay region and ffap-file-at-point and expecting the
filename inside '{}' would be a good starting point.
