WordPress自定义标题

Question

I am currently using custom header image with randomize uploaded image option. It's working fine. Every time I reload the page it header image changes to new one. Is there a way to change that images manually like setting a timer. I'm new to wordpress. My current code is like this

In functions.php

$args = array(
'width'         => 1856,
'height'        => 448,
'default-image' => 'http://wordpress/wp-content/uploads/2015/02/mbuntu-11.jpg',
'uploads'       => true,);

add_theme_support( 'custom-header', $args );

And in header.php

<header class="intro-header" style="background-image: url('<?php header_image(); ?>')">

Add multiple images on the custom theme page. Go to -> theme customize -> header images -> add images and save. Now check on your page it's working like slider.
