detect plugin

I've created an html page and I am looking for a way to show a .swf if the visitor has the flash plug in OR an alternate image if the visitor doesn't have the plug
in.

Anyone have the html for this?

Thanks

Marty

You can but it's browser and platform specific! Best thing to do is create two pages one with flash the other with an alternative image!
This link will create a html page for you:

http://www.flashplanet.com/generate/redir/form.htm

You will be able to paste the JavaScript into your redirect page!

now saying that , the flashplanet one doesnt work all the time, i was on an old computer with an old plugin, and it still let redirected me to the main site, so i had to go and download the flashplugin myself!
