Flash implementation

Hi,
So I have implemented a way to display a flash movie into bbcode.
It uses the following code to display the movie :

      <o bject
        t ype="application/x-shockwave-flash"
        d ata="(flash movie path)"
        w idth="width"
        h eight="height">

      <p aram
        n ame="movie"
        v alue="(flash movie path)" />
      </object>

No codebase, so it does not ask to download new flash version if required, but that is the only way to be able to use relative path for flash movies.

It is called like this [flash=widthxheight]flashurl[/flash]

Tell me if you think of some improvements...
