thumbs doesn't show next image

[Dieter Wilhelm]

Dear Emacs maintainers

Typing <next> (thumbs-next-image) in an image buffer gives me the
following message in the mini-buffer:
          "Wrong type argument: number-or-marker-p, nil"
and not the next image.
          
I think the problem stems from the thumbs-show-image-num function in
thumbs.el (current cvs revision 1.22).

Thank you for your work

      Dieter
