Nevermind, I figured it out!
I had changed the color of the image in the header editor in the admin side. I hit the Default colors button, and the image showed up! I wonder if this would have worked for Miked24.
I’m in a very similar situation. I’ve tried everything on that link, and I can’t get the header image to change. I can get the footer image to change using the exact same method.
My wordpress install is at: http://www.jeffthefish.com/wordpress_jason
I’ve got this in my stylesheet:
#header {
background: #eee url(‘images/jeffheader.jpg’) no-repeat bottom center;
}
