JQuery :: JCarousel External Control As Pagination

I have a couple of problems using jCarousel, and was hoping someone here might lead me to a solution. First of all, can I change the way the External Control function works? I am guessing that I "only" need to edit the javascript file, but having little knowledge of it, I chose not to. What I want to do, is use the External Controls as a pagination, so rather than being a navigation for each image, I would like it to navigate from one page of visible images, to another. More or less, I accomplished it by setting the value inside the <li></ li> to the number I wanted to navigate to.

However, this resulted in ridiculous number always increasing by the number of visible items (have a massive amount of images loaded).

So really, the question is:How can I navigate to a specific image in the carousel using a onclick function? Which brings me to the other problem, the External Controls behave as a list of navigation-buttons. If my carousel shows 500 images, it will generate 500 buttons for navigating. How can I automatically shorten it (as the Pagination Plugin does; [url])? Thinking about it, making such a pagination would be much easier if I knew how to solve the first problem.
