在Wordpress中修改网页

I am a wp beginner and I'm trying to modify webpages for use on my website. I have created a child theme and it appears in my wp dashboard. I have uploaded the images I wish to use via ftp onto my server. I have modified the coding on several of my child theme pages to include my images but nothing is showing up.

This code is from my custom-header.php page-

<?php $header_image = get_header_image();
    if ( ! empty( $header_image ) ) { ?>
        <a href="<?php echo esc_url( home_url( '/' ) ); ?>" title="<?php echo esc_attr( get_bloginfo( 'name', 'display' ) ); ?>" rel="home">
            **<img src="<?php echo get_template_directory_uri();?>/Legion-Scotland.jpg">?>" alt="Legion-Logo" />**
        </a>
<?php } // if ( ! empty( $header_image ) ) ?>

Any help would be MOST appreciated as this is for an overdue college project.

Thanks

You have a typo at

<img src="<?php echo get_template_directory_uri();?>/Legion-Scotland.jpg">?>" alt="Legion-Logo" />

Replace it as

<img src="<?php echo get_template_directory_uri();?>/Legion-Scotland.jpg" alt="Legion-Logo" />
