Как добавить курсовую навигацию к слайдеру

Question

Я создал простой слайдер затухания и получил его работу. Я хочу динамически включать круги навигации пули в слайдер и динамически ссылаться на изображения, которые находятся в слайде, но я считаю это слишком сложным. На данный момент я вручную разместил в пуле навигационные круги

Может кто-нибудь мне помочь? Thankyou

вот моя скрипка http://jsfiddle.net/kingkhan/f5zBy/60/

Updated Fiddle.

Я просто добавил атрибут данных к ссылкам в nav-thumb. Когда они нажимаются, это значение считывается, и слайд показывает изображение.
