I think you are close.


#+BEGIN_SRC org :exports none
#+name: imtable

This gives you the images in a form you can view and a way to access the
links so you can export them in a different form.

For example,

#+BEGIN_SRC emacs-lisp :var a=imtable :exports results :results raw
  (mapconcat (lambda(y) 
                (lambda(x) (org-export-string-as x 'latex t)) y "")) a "")

exports as 


when the elements in the table are the image paths img*.png as shown.
