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))
