About rails AJAX album/gallery helper

Greetings all,

  I am recently seeking an album/gallery helper for my rails
application and it seems a lightbox helper [1] is quite good, but
unfortunately the svn repo seems invalid, Could anyone send me the
newest copy of this helper or just introduce me a better one? Thanks
very much!
