The following script determines the existence and version information of the Flash Player plug-in.
This applies to Netscape, Firefox, Mozilla, Safari, Opera, and all other browsers 
that support the Netscape Plug-in API and a way to interrogate it using browser scripting:

/********************
After you determine which browser your script is running, run through each of these scripts
until you find the latest version of the player installed.

The following script starts with a high version number (25) and runs through the proper script
for each potential version to determine if it exists on the client. Once the script gets a valid return value,
it sets the value of versionStr to the installed version:

At this point you can take this value and make sure your content can be displayed properly in the browser.
For example, if your content requires Flash Player 6r65, you could use the following script
in conjunction with the scripts above to determine if the client has Flash Player and the proper version:
*********************/


// If called with no parameters this function returns a floating point value 
// which should be the version of the Flash Player or 0.0 
// ex: Flash Player 6r65 returns 6.65
// If called with reqMajorVer, reqMinorVer this function returns true if that version or greater is installed
function DetectFlashVer(reqMajorVer, reqMinorVer) 
{
      reqVer = parseFloat(reqMajorVer + "." + reqMinorVer);
      // loop backwards through the versions until we find the newest version      
      for (i=25;i>0;i--) {
