Change Your WordPress Login Logo

Here’s a handy php snippet to pop in your themes functions.php file which will replace the WordPress logo on the login page for your blog. Change the /images/you-login-logo.png to point to your logo. 274px width x 63px height will be a perfect swap.

/** this function swaps the login page logo **/

function my_login_logo() { 
  echo '<style type="text/css">
        body.login div#login h1 a {
            background-image: url('. get_stylesheet_directory_uri() './images/your-login-logo.png);
            padding-bottom: 30px;
        }
    </style>';
}

add_action( 'login_enqueue_scripts', 'my_login_logo' );

Easy as that!
