Drupal 7 is here, but getting a slideshow to work isn't that simple at the moment. Usualy I user the views carousel module, but they aren't making any new versions because the jCarousel module has identical features starting from the 2.x version. But ... the views integration isn't ready yet. Warning, this article is only for jCarousel versie 7.x-2.2-alpha1. Newer versions should already have it working.
