Hi,

I see YUI slideshow: http://freshcutsd.com/yui-slideshow/#demo as part of the library http://yuilibrary.com/gallery/show/yui-slideshow

Also here was asked about YUI slideshow: http://groups.drupal.org/node/20384#comment-449999
Please add YUI slideshow to the widgets.

Thanks a lot in advance!
Greetings, Martijn
