//1) specify path to image//图片的路径      
 var imagepath="http://www.xintv.com/ad/index/tianyi.gif"     
 
 //2) specify image dimensions//图片的大小      
 var imagewidth=150      //图片宽 
 var imageheight=113    //图片高     
 
 //3) change this to adjust speed (lower is slower)//飞行速度建议别改太快，会卡      
 var speed=3;      
 
 //4) configure what should happen when user clicks on image      
 //A value of "dismiss" will dismiss it, while a URL will cause the browser to navigate to it      字串1 
 var imageclick="http://rad.vnet.cn/AdTrace.aspx?orderitemid=4713&url=http://sh.vnet.cn//elive/download/pc_elive_1.1.rar&location=SH"      
 
 //5) Finally, configure when the image should automatically disappear, in seconds (0=perpetual)
