Hide Image Titles on Hover

Hi,

When we hover over the images it shows the image title under which we have saved the image in the library.

How can we hide it permanently?

I have used the following code in function.php but it didn’t work.

function add_custom_script(){
?>
<script>
jQuery(window).load(function(){
jQuery(‘img’).removeAttr(‘title’);
});
</script>
<?php
}
add_action(‘wp_footer’, ‘add_custom_script’);
*/
Please can you recommend a solution as it looks unprofessional when it shows the file names.

Looking forward to your response.

Kind regards,
