Stylesheet not working for theme

I made a simple theme and I could not get the stylesheet to work.

This is what I have:

<link rel=”stylesheet” type=”text/css” media=”all” href=”<?php bloginfo( ‘stylesheet_url’ ); ?>” />

It should link to the style.css in the theme’s folder, right?

I also cannot get any of the images to load.

<img src=”images/banner.jpg” alt=”banner” />

I assumed that I didn’t have to put the whole URL if it is in the same folder.

Thank you in advance!
