Thank you for your prompt response. I am new to WP, having moved from the much simpler environment of GoDaddy Website Builder, which did not have the capability of WP.
Following advice on creating a child theme and the suggestion above, the file C:\inetpub\wwwroot\AlekaConsulting\AlekaConsulting\wp-content\themes\twentysixteen-child\functions.php now contains
<?php
date_default_timezone_set("Australia/Sydney");
add_action( 'wp_enqueue_scripts', 'my_theme_enqueue_styles' );
add_theme_support( 'custom-header', array(
'video' => true,
) );
function my_theme_enqueue_styles() {
$parent_style = 'twentysixteen-style'; // This is 'twentysixteen-style' for the Twenty Sixteen theme.
wp_enqueue_style( $parent_style, get_template_directory_uri() . '/style.css' );
wp_enqueue_style( 'child-style',
get_stylesheet_directory_uri() . '/style.css',
array( $parent_style ),
wp_get_theme()->get('Version')
);
}
function current_time_date(){
$dt = current_time('timestamp');
return date('F jS, Y, H:i:s',$dt);
}
add_shortcode( 'time_date', 'current_time_date' );
function themename_custom_header_setup() {
$defaults = array(
// Default Header Image to display
'default-image' => get_template_directory_uri() . '/images/headers/default.jpg',
// Display the header text along with the image
'header-text' => false,
// Header text color default
'default-text-color' => '000',
// Header image width (in pixels)
'width' => 1000,
// Header image height (in pixels)
'height' => 198,
// Header image random rotation default
'random-default' => false,
// Enable upload of image file in admin
'uploads' => false,
// function to be called in theme head section
'wp-head-callback' => 'wphead_cb',
// function to be called in preview page head section
'admin-head-callback' => 'adminhead_cb',
// function to produce preview markup in the admin screen
'admin-preview-callback' => 'adminpreview_cb',
);
}
add_action( 'after_setup_theme', 'themename_custom_header_setup' );
add_theme_support( 'custom-header', array(
'video' => true,
) );
There is no Header.php file in C:\inetpub\wwwroot\AlekaConsulting\AlekaConsulting\wp-content\themes\twentysixteen-child. I copied the header.php file from C:\inetpub\wwwroot\AlekaConsulting\AlekaConsulting\wp-content\themes\twentysixteen and amended it to the following:
<?php
/**
* The template for displaying the header
*
* Displays all of the head element and everything up until the "site-content" div.
*
* @package WordPress
* @subpackage Twenty_Sixteen
* @since Twenty Sixteen 1.0
*/

However, when I go to customize Header Media I only have the option to select an image from the media libary, not a link to a video. Selecting a different image also does not change the background image.
