[SOLVED] Pretty Permalinks, htaccess, and the ata-images folder

Hello and thanks to everyone that has contributed to this forum. I'm learning WP and have had many of my questions answered here just browsing through posts. But I finally have a question I haven't found the answer to:

I just changed to Pretty Permalinks, and updated my htaccess file manually. On the homepage everything looks fine. However if I click on a post or category, the background and a few other images aren't coming up. So it would seem that it doesn't know to look in the 'ata-images' folder for these other pages.

My wordpress url is: systemaddict.webfactional.com
My site url is: systemaddict.org

Any help is greatly appreciated.
