Randomly change image based on directory contents???

[Fuzemmo]

Is it possible to do the following?

I have an image with say an id="sponsor" on my web page. I need to be able to randomly pick a new image to display in that spot say every 20 seconds. I pick the image from a list of jpg files in the imgSponsors directory on the server. Is it possible for me to get that directory list on the server, and then client-side just swap the image every N seconds?

Thanks,
Jim

something like this ought to do it... you would need to generate the "imgs" array server-side:

var imgs = new Array(
	"a.jpg",
	"b.jpg",
	"c.jpg",
	"d.jpg",
	"e.jpg"
);

function swapImg() {
	var img = imgs[ Math.round(Math.random() * (imgs.length - 1)) ];
	document.getElementById("sponsor").src = "imgSponsors/" + img;
}
