Hide image file names in Gallery / Portfolio

remember that since jQuery 3.0 and later will not have the

jQuery(window).load(function(){

it is deprecated since jQuery 1.8 and removed since jQuery 3.0
you must now use:

jQuery(window).on('load', function(){

And if you don’t just temporarily remove the titles on hover, then remember for any lightboxes not to use the title for the caption.

this here is a temporarly remove of the title tag
you must adopt your selector to what you need ! ( var links )

function temporary_removal_title_tags(){
?>
<script>
  window.onload = function() {
    //var links = document.querySelectorAll('a,img,div[title]');
      var links = document.getElementsByTagName("img");
      for (var i = 0; i < links.length; i++) {
          var link = links[i];
          link.onmouseover = function() {
              this.setAttribute("org_title", this.title);
              this.title = "";
          };
          link.onmouseout = function() {
              this.title = this.getAttribute("org_title");
          };
          link.onclick = function() {
              this.title = this.getAttribute("org_title");
          };
      }
  };
</script>
<?php
}
add_action('wp_footer', 'temporary_removal_title_tags');

you see what the code does: it saves the original title to another attribute : org_title
now if the mouse hovers – the title is empty but the original title is saved to another attribute.
if you leave it ( mouseout ) the title is there again.
And on click the title will be there for lightbox captions.
the code above is only for images – but you see the commented line – you can have more selctors here.
you can use the selectors Nikko mentioned above.

See in action here with the enfold tooltip on the images: https://webers-testseite.de/gallery-with-8-images/
normal behavior is here on Gallery with preview ( hove the thumbnails ): https://kriesi.at/themes/enfold-2017/elements/gallery/

there will be both : enfold tooltip and browser tooltip by titles
