i'm guessing this is part of the licensing. plus it looks like you have to embed the flash app into your web page, which basically means the code is kept on an external site.
however there's loads of free javascript slide shows out their, just google "javascrip slide show", it's also a good way of learning, seeing the code and working out what bit does what...
Hope this helps, i know it's not quite the solution you were hoping for...
Cheers
