Issue with Lightbox Titles

We are currently suppressing images titles when you hover over them as this is annoying my client. We have the following code in the child functions.php file:
<?php
add_filter(‘avf_logo_subtext’, ‘kriesi_logo_addition’);
function kriesi_logo_addition($sub) {
$sub .= ‘<div class=”logo-title”>RESPECTACLE <span>COMPANY</span></div>’;
$sub .= ‘<div class=”logo-subtitle”>Tel: 01858 433 577</div>’;
return $sub;
}
$avia_config[‘imgSize’][‘featured’] = array(‘width’=>1500, ‘height’=>555 ); // images for fullsize pages and fullsize slider
add_filter( ‘gform_enable_field_label_visibility_settings’, ‘__return_true’ );
function remove_title_attr(){
?>
<script>
jQuery(window).load(function(){
jQuery(‘a’).removeAttr(‘title’);
jQuery(‘img’).removeAttr(‘title’);
});
</script>
<?php
}
add_action(‘wp_footer’, ‘remove_title_attr’);
?>
Although this works and suppresses the image tiltes on hover my client wants the titles to show in the lightbox. I have found if I remove the remove_title_attr this shows the titles in the lightbox. What we need is for the hover tiltles on the images to be removed and the lightbox titles to show can you please help.
