I can't get jcarousel to work

Issue Summary

I've downloaded the jcarousel block and the jcarousel. I've copied jcarousel into the jcarousel block folder as I've seen advised in other forum posts. From there, I can't seem to add images. I can't even find a step by step instruction online on how to use this tool. Do I upload the pictures onto another site like flickr and jcarousel pulls it from there? Do I upload the photos from my site? I tried to add the jcarousel block to my left column of Marinelli and that won't work either. Thanks for any help.
