JavaScript

I have found a carousel that i will be working with it is what i need apart from one thing. How do make it loop instead of speeding back to the first slide. http://jsfiddle.net/PGcY2/

It won’t be possible without altering the carousel code (you can’t just pass it an option of loop: false or something).

Is it intended to be a responsive slider or are the slides a fixed width?
