//在头文件或尾文件中用<script src="××××.js"></SCRIPT> 语句调用
//左边
var left_img='<a href=http://www.busfly.cn/ target=_blank><img src=http://pic.hjsm.tom.com/index/skin/newmode/pho_vip.jpg border=0></a><br><br><a href=http://www.busfly.cn target=_blank><img src=http://pic.hjsm.tom.com/index/skin/newmode/pho_vip.jpg border=0></a>';
