// U can change this number to check specific version of flash

var MM_contentVersion = 6;

var plugin = (navigator.mimeTypes && navigator.mimeTypes["application/x-shockwave-flash"]) ?

navigator.mimeTypes["application/x-shockwave-flash"].enabledPlugin : 0;

if ( plugin ) {

var words = navigator.plugins["Shockwave Flash"].description.split(" ");

for (var i = 0; i < words.length; ++i){

if (isNaN(parseInt(words[i])))

continue;

var MM_PluginVersion = words[i];

}

var MM_FlashCanPlay = MM_PluginVersion >= MM_contentVersion;

}

else if( navigator.userAgent && navigator.userAgent.indexOf("MSIE")>=0 &&

(navigator.appVersion.indexOf("Win") != -1) ) {

//FS hide this from IE4.5 Mac by splitting the tag

document.write('<SCR' + 'IPT LANGUAGE=VBScript\> \n');

document.write('on error resume next \n');

document.write('MM_FlashCanPlay = ( IsObject(CreateObject("ShockwaveFlash.ShockwaveFlash." & MM_contentVersion)))\n');

document.write('</SCR' + 'IPT\> \n');
