Adding Header Background Image Support

Adding WordPress 3+ Header Image Support is simple. You can drop the following code in the functions.php file and it will get you started.

// header image define
if (!defined('NO_HEADER_TEXT')) { define('NO_HEADER_TEXT', true ); } // no header text
if (!defined('HEADER_TEXTCOLOR')) { define('HEADER_TEXTCOLOR', 'ffffff'); } // header text color
if (!defined('HEADER_IMAGE')) { define('HEADER_IMAGE', get_template_directory_uri() . '/library/images/default_header.jpg'); } // default header image
if (!defined('HEADER_IMAGE_WIDTH')) { define('HEADER_IMAGE_WIDTH', 960); } // the width of the logo
if (!defined('HEADER_IMAGE_HEIGHT')) { define('HEADER_IMAGE_HEIGHT', 150); } // the height of the logo
	
// gets included in the site header
function bones_header_style() { ?>
    <style type="text/css"> header[role=banner] { background: url(<?php header_image(); ?>); } </style><?php
}
// gets included in the admin header
function admin_header_style() { ?>
    <style type="text/css">
	#headimg {
	    width: <?php echo HEADER_IMAGE_WIDTH; ?>px;
	    height: <?php echo HEADER_IMAGE_HEIGHT; ?>px;
	}
    </style>
<?php }

add_custom_image_header('header_style', 'admin_header_style');
