i have the same problem with "bulletz"
(old topics called "No Images in themes" 7 motnths ago)
i cannot see any screenshoots in my theme. Not that, even i can't see the wordpress logo in my footer of "wp-admin" page.
My server also uses Fantastico to install wordpress.
I have instance running on http://jesusforyouth.org/.
that is running great too.
now i want to run another wordpress in my subdomain http://cornet.jesusforyouth.org/
after installed the wordpress in my subdomain, I can't get any pictures to show up.
