Image Title on Hover

Hi, I’ve tried multiple codes to remove the image title on mouse hover, but it’s not disappearing.

It doesn’t show up if I’m logged into wp-admin, but once I logout I still see it.

Using Chrome on Mac

Codes I’ve tried

Quick CSS

/*Remove image title on hover*/
img[title] {
        pointer-events: none;
    }

Functions.php

/*Remove image alt text on hover*/
function remove_title_attr(){
?>
 <script>
jQuery(window).on('load', function(){
jQuery('#wrap_all a').removeAttr('title');
jQuery('#wrap_all img').removeAttr('title');
});
 </script>
<?php
}
add_action('wp_footer', 'remove_title_attr');
