//右侧浮动广告代码（QQ对话栏）：
theFloaters.addItem('followDiv1','document.body.clientWidth-140',195,'<a target="_blank" href="/msgrd?v=3&uin=2357484552&site=qq&menu=yes"><img border="0" src="/pa?p=2:2357484552:53" alt="give me message" title="click here"></a>');
//左侧浮动广告代码（可调用flash或图片）：
theFloaters.addItem('followDiv2',6,80,'<EMBED src="..." quality=high WIDTH=100 HEIGHT=300 TYPE=application/x-shockwave-flash id=ad wmode=opaque></EMBED>');

//广告图片的调用方法：
//<a href=/lanren/ target=_blank><img src=images/ad_100x300.jpg border=0></a>。
