need sophisticated slider content

We got new slider which needs to have nice banner in flash or just image ( i am not really sure yet. Its for the main page of product comparison site, so could have products, but also info about the website, or both.) if we gone have products i want them to be dynamically loaded from the database, so need function for homepage yes or no or just text and images which can be indexed by google the slider right now is a paid version, but i want that replaced for something like [login to view URL] , so with next and previous arrow. Give me some good ideas please\\flash could also be nice, if it loads products from xml we can change
