Custom Header Image

[ghost]

I have a question I've just installed your theme and love it so far, the only problem I have is when I go to the theme customizer and add a new Header Image it won't show up. Is there something I missed or do I have to add some code into the theme. Thank you for your help.

This is part of my header.php for example

@ghost, Header Image is used as background image for the masthead in WordPress default themes.

Header Image can be used for a logo image. This snippet is from Automattic _s underscores theme:

<?php if ( get_header_image() ) : ?>
<a href="<?php echo esc_url( home_url( '/' ) ); ?>" rel="home">
<img src="<?php header_image(); ?>" width="<?php echo esc_attr( get_custom_header()->width ); ?>" height="<?php echo esc_attr( get_custom_header()->height ); ?>" alt="" />
</a>
<?php endif; // End header image check. ?>
