Custom Header Image

To configure a custom header image using the Genesis Framework, you can use this snippet:

add_theme_support( 'genesis-custom-header', array( 
  'width' => 960, 
  'height' => 100 
) );

You may also use the WordPress built-in custom-header, that allows to configure some more things:

add_theme_support( 'custom-header', array(
  'width'       => 320,
  'height'      => 65,
  'header-selector' => '.site-header .title-area',
  'header-text' => false
) );
