Remove width & height attributes from images in posts

Looking to remove the width and height attributes from images in your posts? Is this because you are using a responsive wordpress theme. Just add this snippet to the functions.php of your wordpress theme and all of the width and height attributes will be removed from your images.

add_filter( 'post_thumbnail_html', 'remove_wps_width_attribute', 10 );
add_filter( 'image_send_to_editor', 'remove_wps_width_attribute', 10 );
function remove_wps_width_attribute( $html ) {
    $html = preg_replace( '/(width|height)=\"\d*\"\s/', "", $html );
    return $html;

    height: auto;
