JQuery :: Extending Background Stretcher Plug In And Add Navigation?

I am working wiht this JQuery plug in that now one of my clients wants to turn it into a slideshow feature. I am not that familiar with JQuery plug ins so I wanted to get some input from some of you.

On the header of my html page:

Code:

$(document).bgStretcher({
images: ['1.jpg', '2.jpg', '3.jpg', '4.jpg'],
imageWidth: 1668, imageHeight: 1035, nextSlideDelay: 3000, slideShowSpeed: 4000
});

I was able to add a click handler to trigger the a function on the plugin called loadslide().

Code:

$(document).ready(function ($) {
$('.slideNo').each(function (i) {
$(this).click(function () {
loadSlide(i);

[Code].....
