adding these calls:

DEFUN ("clear-image-cache", Fclear_image_cache, Sclear_image_cache,
      0, 1, 0,
      doc: /* Clear the image cache of FRAME.
FRAME nil or omitted means use the selected frame.
FRAME t means clear the image caches of all frames.  */)
    (frame)
    Lisp_Object frame;
{
 if (EQ (frame, Qt))
   {
     Lisp_Object tail;
    fprintf(stderr, "I am here1\n");
     FOR_EACH_FRAME (tail, frame)
        if (FRAME_WINDOW_P (XFRAME (frame)))
    fprintf(stderr, "I am here2\n");
          clear_image_cache (XFRAME (frame), 1);
   }
 else
    fprintf(stderr, "I am here3\n");
   clear_image_cache (check_x_frame (frame), 1);

 return Qnil;
}

results in

I am here1
I am here2

every time I do M-:(clear-image-cache t)
