logo image instead of site title

https://css-tricks.com/css-image-replacement/ ?

no no no.

This works:

in header.php look for:

<span>
    <a>" title="<?php echo esc_attr( get_bloginfo( 'name', 'display' ) ); ?>" rel="home"><?php bloginfo( 'name' ); ?></a>
    </span>

Replace with:

<span>
    <div id="logo"> <a>"><img src="https://www.your_URL.com/images/eco.jpg" alt="Your text" /></a></div>
    </span>

Hopefully you did that in a Child Theme.

uh yes… zzz

I fixed that in my next version. In the next version you can use Theme Customizer to upload your logo.
