   Before using this, check out get_header_image_tag() first. That’s a new function in 4.4 that’ll return an tag including the srcset attributes for responsive images.

   get_header_image_tag()

Example

<img src="<?php echo esc_url( get_header_image() ); ?>" alt="<?php echo esc_attr( get_bloginfo( 'title' ) ) ); ?>" />
