Lightroom can create web gallery of a similar type.
JAlbum is another useful application for generating web galleries. Very useful and most of all is free. :)
Lightroom can create a slide show for the web but i think you cannot add sound to it.
windows movie maker is an option i might go for but i was
wondering which adobe product does the silde show with sound for the web
By the way. Windows Movie Maker will create a movie. Lightroom, JAlbum or the rest will create a flash/xml gallery which is way better then an AVI in terms of quality and speed.
