The jCarousel module is most commonly used with the Views module to turn listings of images or other content into a carousel.
- Install the Views module (http://drupal.org/project/views) on your Drupal site if you have not already.
- Add a new view at Administration -> Structure -> Views (admin/structure/views).
- Change the "Display format" of the view to "jCarousel". Disable the "Use pager" option which cannot be used with the jCarousel style. Click the "Continue & Edit" button to configure the rest of the View.
- Click on the "Settings" link next to the jCarousel Format to configure the options for the carousel such as the animation speed and skin.
