php上面的广告，高手能不能帮忙下如何不显示？
一个php的论坛，在右下角有这样的广告其源文件下面的代码为：
</script>
<script type="text/javascript" language="JavaScript" src="js/pw_jobcenter.js"></script>
<script src="js/float.js" language="javascript"></script>
<script language="javascript" defer>
var oldWindowOnloadFunc = window.onload;
window.onload = function () {
if (oldWindowOnloadFunc != undefined) {
oldWindowOnloadFunc();
}
var LeftCode = RightCode = '';
/**/
var popParam={'title':'幸运二泉网，好运天天上','winHeight':276,'winWidth':252,'winClose':10};
var popCode='<a title="幸运二泉网，好运天天上" href="http://bbs. target="_blank"><img src="http://bbs. width="250" height="250"/></a>';
ShowPop(popParam,popCode);
/**/
imgloops.imginit();/*多图片轮播*/
}
</script>
<script language="JavaScript" src="/js/pw_init.js"></script>
如何让电脑上不显示这个小广告啊？ 每次刷新都有，看的很心烦
