Serve static content from a cookieless domain, missing icons

Hi
i wanted to make te results in gtmetrix of static content from a cookieless domain giving 0 as result

so i created a static domain pointing to wp-content and added the following to wp-config

define("WP_CONTENT_URL", "http://static.domainname.com");
define("COOKIE_DOMAIN", "www.domainname.com");
define("WP_PLUGIN_URL", "http://static.domainname.com/plugins");

but images show then as static source but the theme dont show his font-icons (entypo-fontello) anymore, what can i do about that?
