Replacing swf with jpg/gif/etc. when browser doesn

firstly thank you for aiding me.
I am working on my churches website and I am trying to work a script that uses the swf file if the the browser has flash and uses gif file if it doesn’t

here’s the following code :

[CODE]<script language=”javascript 1.1″>
var MM_contentVersion = 8;
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)) {
document.write(‘<SCR’ + ‘IPT LANGUAGE=VBScript> n’); //FS hide this from IE4.5 Mac by splitting the tag
document.write(‘on error resume next n’);
document.write(‘MM_FlashCanPlay = ( IsObject(CreateObject(“ShockwaveFlash.ShockwaveFlash.” & MM_contentVersion)))n’);
document.write(‘</SCR’ + ‘IPT> n’);
}
if ( MM_FlashCanPlay ) {
document.write(‘<OBJECT classid=”clsid:D27CDB6E-AE6D-11cf-96B8-444553540000″‘);
document.write(‘codebase=”http://download.macromedia.com/pub/shockwave/cabs/flash/swflash.cab#version=6,0,0,0″ ‘);
document.write(‘ ID=”Untitled-1″ WIDTH=”550″ HEIGHT=”400″ ALIGN=””>’);
document.write(‘ <PARAM NAME=movie VALUE=”ban2.swf”> <PARAM NAME=quality VALUE=high> <PARAM NAME=bgcolor VALUE=#FFFFFF> ‘);
document.write(‘ <EMBED src=”ban2.swf” quality=high bgcolor=#FFFFFF ‘);
document.write(‘ swLiveConnect=FALSE WIDTH=”550″ HEIGHT=”400″ NAME=”Untitled-1″ ALIGN=””‘);
document.write(‘ TYPE=”application/x-shockwave-flash” PLUGINSPAGE=”http://www.macromedia.com/go/getflashplayer”>’);
document.write(‘ </EMBED>’);
document.write(‘ </OBJECT>’);
} else{
document.write(‘<IMG SRC=”LACpage_01.jpg” WIDTH=”550″ HEIGHT=”400″ usemap=”#Untitled-1″ BORDER=0>’);
}
</script>
[/CODE]
