I know from your other post here that you use Moodle 1.9 and it makes no difference which way you upload your files to the server, the themes don't appear to work.
Can you actually see the themes in the Theme selector page or not?
Or is it just that you cannot see the images once the theme is selected?
What kind of server are you using? Is it a shared hosting package you have, or are you using a desktop server like WAMP or LAMP or XAMPP, or perhaps you are a MAC user?
A little more information would be helpful.
EDIT! I'm just adding this as an after thought. Any chance you could get me a username & password to your Moodle site so I could take a look? It might be something that I can fix...but need to see where theings are going wrong.
