Question

I'm looking for custom code to remove fields on user profile like you see in the pictures : I would also like to replace Gravatar images with simple photos from the media library:

Answer 1

Part 1

Create wpse_admin_user.css file and put it in your current theme, where style.css is:

tr.user-admin-color-wrap,
tr.user-admin-bar-front-wrap {
    display: none;
}

Add this code to your theme's functions.php:

function wpse_user_admin_script() {
    wp_register_style( 'wpse_admin_user_css', get_stylesheet_directory_uri() . '/wpse_admin_user.css' );
    wp_enqueue_style( 'wpse_admin_user_css' );  
}
add_action( 'admin_enqueue_scripts', 'wpse_user_admin_script' );

Part 2

Install and activate Custom User Profile Photo plugin. You will be able to use pictures from media library.
