If you want Flash elements on your webpage you can design them or buy a flash template, but you must remember that to be able to see your Flash online the visitor will need the appropriate Flash player installed into their Browser. So, if you add a movie in Flash 5 the visitor will need the Flash 5 Player - or a more recent version.

If you create a Flash MX movie the Browser needs the Flash 6 Player and Flash MX 2004 needs the Flash 7 Player. Standard browsers like Internet Explorer come with a Flash Player installed. Of course there is no guarantee it will be the most recent version. When Macromedia brings out a new version of Flash they also bring out a new version of the Flash Player. Nobody has the new Player at first.  The average visitor will not go out of their way to get the new Player or even know what a Flash Player is.

Aside from Flash problems with SEO crawlers, it is often well worth the down side to get the excellent looks that Flash can
deliver.  Does this mean you must create movies in the latest versions of Flash?  The answer is no.  Personally I always use the most widespread technology so that anyone can see it, but push the creativity end of it until it is as hot as I want.

This means build movies in the oldest version of Flash that will be supported in old and new versions of Flash players.  It
can still be a high impact Flash display - and almost everybody sees it without the new download doldrums.
