Do you want to remove width and height attributes from images in posts? This snippet will remove all of the width and height attributes from your images in order to allow a responsive theme to handle the sizing.
Instructions
All you have to do is add this code to your theme’s functions.php file or in a site-specific plugin:
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;
}
Note: If this is your first time adding code snippets in WordPress, then please refer to our guide on how to properly copy / paste code snippets in WordPress, so you don’t accidentally break your site.

Thank You so much.
If you want to do this for responsive purposes a better way would be to resolve this issue with CSS, since CSS overwrites this attributes:
img{
max-width:100%;
height: auto;
}
