@mytaxsite Thanks!

I have done step 1 and uploaded it into the media gallery.

Then I put in the following code in functions.php

$defaults = array(
	'width'                  => 1205,
	'height'                 => 125,
	'flex-height'            => true,
	'flex-width'             => true,
);

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

I was expecting that this will cause the small logo size to expand to the setting above. But it stays the same small default original logo size of the theme.

Note that I am not working in the Child Theme for this time. But once I figure it out, I will reconstruct it in the child theme. I feel this is easier to understand though not the best practice (i know).

Thanks.
