在你网页的适当位置加入以下代码,修改下swf路径就OK
当然你要先有那个FLASH，恩，我下载有了200多个，哈哈，明天再说吧

<Div id="MagicFace" Style="POSITION:absolute;Z-INDEX: 99;visibility:hidden; "></Div>
<SCRIPT LANGUAGE="JavaScript">
<!--
function MM_showHideLayers() { //v6.0

var i,p,v,obj,args=MM_showHideLayers.arguments;
obj=document.getElementById("MagicFace");
for (i=0; i<(args.length-2); i+=3) if (obj) { v=args[i+2];
if (obj.style) { obj=obj.style; v=(v=='show')?'visible':(v=='hide')?'hidden':v; }
obj.visibility=v; }
}

function DispMagicEmot(MagicID,H,W){
 MagicFaceUrl = "FLASH魔法表情地址";
 document.getElementById("MagicFace").innerHTML = '<OBJECT codeBase="http://download.macromedia.com/pub/shockwave/cabs/flash/swflash.cab#version=4,0,2,0" classid="clsid:D27CDB6E-AE6D-11cf-96B8-444553540000" width="' + W + '" height="' + H + '"><PARAM NAME=movie VALUE="'+ MagicFaceUrl +'"><param name=menu value=false><PARAM NAME=quality VALUE=high><PARAM NAME=play VALUE=false><param name="wmode" value="transparent"><embed src="' + MagicFaceUrl +'" quality="high" pluginspage="http://www.macromedia.com/shockwave/download/index.cgi?P1_Prod_Version=ShockwaveFlash" type="application/x-shockwave-flash" width="' + W + '" height="' + H + '"></embed>';
 document.getElementById("MagicFace").style.top = (document.body.scrollTop+((document.body.clientHeight-300)/2))+"px";
 document.getElementById("MagicFace").style.left = (document.body.scrollLeft+((document.body.clientWidth-480)/2))+"px";
 document.getElementById("MagicFace").style.visibility = 'visible';
 MagicID += Math.random();
 setTimeout("MM_showHideLayers('MagicFace','','hidden')",8000);
 NowMeID = MagicID;
}

DispMagicEmot(144,350,500);
//-->
</SCRIPT>
