oh my god…THANK YOU!!!!!!!!!!!!!!!!!!!!!!
something that should be the simplest thing to do, yet is frustratingly difficult to find support for. this forum is filled with questions about replacing the kubrick header. this is by far the best solution.
** UPDATE FOR WORDPRESS 2.5 **
Replace the kubrickheader.jpg with your own image. Then go to the dashboard – design – header image & color – advanced – select default colors – update header.
