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.
