Thank you for your help Ben.

But my client think this is not the solution.
I have to know if flash is install. If not then I display a gif.

>>I am looking for a VB script or JAVA script that can tell if Flash is install in the browse.
>>
>>A solution with ASP can also work.
>>
>>This gold is the display an alternative to the user when flash is not installed.

>The simplest solution I have see to this would be to embed a flash movie on the page. At the end of the movie, have it force the user to load another page. (I don't have flash on this machine so I can't tell you the action name, but it's there)

>If the user does have flash, it will automatically forward them to the flash page!

>Hope this helps.
