Full width and responsive header image

You could copy header.php to child theme and move this code outside #header.

<?php if ( get_header_image() ) { /* if header image is set use it as logo. */ ?>

<h1 id="site-title"><a href="<?php echo home_url(); ?>" title="<?php echo esc_attr( get_bloginfo( 'name' ) ); ?>"><img src="<?php header_image(); ?>" height="<?php echo get_custom_header()->height; ?>" width="<?php echo get_custom_header()->width; ?>" alt="<?php echo esc_attr( get_bloginfo( 'name' ) ); ?>" /></a></h1>

<?php } else { ?>

<h1 id="site-title"><a href="<?php echo home_url(); ?>" title="<?php echo esc_attr( get_bloginfo( 'name' ) ); ?>"><?php bloginfo( 'name' ); ?></a></h1>

<?php }  ?>

You need some css styling after that.

Thanks a lot! It works! ??

I set [#site-title img] width to 100%. Now the header image remains a little bit stretched. What should be the optimal image length in pixels to avoid stretching and loosing sharpness? 1920px?

Yep something like that.

Hi, is there a way to use a standard 900 wide header on Path theme?

What do you mean when you say child theme?

And do I delete the header template and just add that snippet up there to function.php?

Thanks, just a little confused and trying to understand your instructions.
