Here the Flash movie will appear.

Flash Gives a site Rich Media Experience, you can include Animation sound in one place.

Normally Flash is Used to make whole website or can be used to put banners in website.

If you are looking for Search Engine optimization in website than Full Flash websites are not advisable as search engine crawlers dont crawl the flash websites.

There are other tools like real media player and windows media player who provided rich media experience but they are tooooo heavy in loading compare to flash
