Dear Jimmy,
in this case the reason is most probably your hosting server’s settings which prevent the Timthumb module from displaying the images correctly (I’ve double checked on the theme demo and the carousel works fine, see this test page).
Let us try one more thing: please download this file from my repository, unzip it, and upload into the same folder as before, re-writing the existing file. Then refresh the website, create a new page, attach several images to it, and try inserting the jCarousel shortcode anew. Then send me the URL of that page to support@satoristudio.net (as far as I remember you did not wish to disclose your website’s URL on the forum).
Sincerely,
Andrew | Satori Studio
