> how to detect flash plugin? and the version of the plugin as well.
> thanks!

  Hey, There are many ways to accomplish this. I've tried a few and had 
the most success with a little download I got from macromedia's site. Use 
the search box and look up "Flash Deployment Kit" It takes a bit to set it 
all up but it covers all your bases. Check out some of the tutorials on 
the Flashkit website http://www.flashkit.com You'll find lots of ideas 
there too. Hope that points you in the right direction, Dave
