//=============================================
//函数功能：网站首页两侧随平米滚动的图片代码
//函数功能：可以插入图片 和网页框架
//函数使用：在需要调用的网页先插入一个层 js其后
//层代码：
//<div id="floater" style="POSITION: relative">
//    <div style="LEFT: -110px; WIDTH: 100px; POSITION: absolute; TOP: 0px; HEIGHT: 250px">
//        <a href="#" target="_blank"><img src="http://pics.taobao.com/bao/album/chl/lottery/2007111-9100-250.gif" border="0" alt="驰名商标"/></a>
//    </div>
//    <div style="LEFT: 778px; WIDTH: 108px; POSITION: absolute; TOP: 0px; HEIGHT: 340px">
//    	<iframe id="QQ_Services" frameborder="0" scrolling="no" width="108px" height="340px" src="/Inc/QQ_Services.htm"></iframe>
//    </div>
//</div>
//注意：层代码在前 JS在后 否则报错
