I just commited a rename of those commands. Also, below is a new
version of `tumme-forward-image' with the changes you asked for.
Please try it out:

(defun tumme-forward-image (&optional arg)
 "Move to next image and display properties.
Optional prefix ARG says how many images to move; default is one
image."
 (interactive "p")
 (let (pos (steps (or arg 1)))
   (dotimes (i steps)
     (if (save-excursion
           (forward-char)
           (while (and (not (eobp))
                       (not (tumme-image-at-point-p)))
             (forward-char))
           (setq pos (point))
           (tumme-image-at-point-p))
         (goto-char pos)
       (error "No more images"))))
 (when tumme-track-movement
   (tumme-track-original-file))
 (tumme-display-thumb-properties))
