该一段JS代码

Question

下面是一段漂浮广告的代码。
//可设置漂浮图片是否为FLASH以及显示大小
var brOK=false;
var mie=false;
var vmin=2;
var vmax=5;
var vr=1;
var timer1;
var ads;
var isflash=0;      //是否为FLASH文件的漂浮 1=是 0=否
var pic="images/01.jpg";     //图片的地址
var alt="请点我吧!";     //鼠标放在图片上时显示的提示文字
var url="http://www.jz123.cn/";  //图片链接的地址
var flashurl="1.swf";   //FLASH文件的路径
var Wimg=80;     //图像的宽度
var Himg=80;     //图像的高度

ads();我想把他该成一个function 根据传递的参数不同，来漂浮不同的图片，和生成不同的连接
传递参数：图片地址，图片高，图片宽，图片URL
