New wp theme doesnt' recognize stylesheet

Hello all. worked up a site in html/php
went to xfr it to wp.
so in the wp > wp-content > themes
I have the folder w/my new theme.
inside the folder I have the css folder w/style.css an images folder/with images
outside of those folder I have the index. php, header.php and footer.php
in the header.php I have:

<link rel="stylesheet" href="<?php bloginfo('stylesheet_url'); ?>" type="text/css" />

and yes in the index.php I have

<?php get_header(); ?>

but it is not bringing up the style sheet i created for this page.
The content is coming through, but the one image and the css is not, the links/folder structure match.

What am I doing wrong please?
thanks

never mind on the style.sheet. copied from notepad++ into the wp editor window now it works.
the image however is still not showing up.
so any adviceā€¦send it over! Is there a separte image function or something?
cheers all.
