js picture rotation and...

I have the attached code rotating some images.

Question 1: How can I add a text box showing some description about the picture (please see the attache image)?
Question 2: How can add the little circles (one per pic) with the one led-up for the current picture?

I hope you can give me a working sample of some sort, if you have any, instead of writing about it.

Thank you.

var imageIndex = 0;

function changeImage() {
	if (imageIndex >= imageArray.length) {
	imageIndex = 0;

var intervalHandle = setInterval(changeImage,5000);

Use a transparent div with the text and position it relative to the image with a higher z-index.

Alternatively just download and use http://wowslider.com/rq/how-to-make-image-scroller-code-title-linked-3O.html
