There is an old adage that a little learning is a dangerous thing and I have spent the last few hours proving that!

I wish to change my wp header to this...http://tinyurl.com/24t2qoh

wp url is KOR-Talk

The style.css sheet is...
and the header.php is...
Can I do this? Can someone guide me to the correct places to insert the url for the new image?

thanks
