//1) specify path to image//图片的路径
var imagepath="../../logo.jpg"

//2) specify image dimensions//图片的大小
var imagewidth=90
var imageheight=30

//3) change this to adjust speed (lower is slower)//速度
var speed=8;

//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
var imageclick="dismiss"

//5) Finally, configure when the image should automatically disappear, in seconds (0=perpetual)
