    Hi,
    I faced an issue when labeling the picture with text containing apostrophe. When you save or update it the gallery is just lost.

    To solve this issue there are several ways. But, I choose to sanitize the image label by modifying in lightbox-slider.php the function called light_box_meta_save()
    $name = $_POST[‘image_label’.$i];
    replaced by
    $name = cleanstr($_POST[‘image_label’.$i]);
    update_post_meta($post_ID, ‘image_label’.$i, $name);
    and adding a function cleanstr which is
    function cleanstr($string) {
    $string = preg_replace(‘/[^A-Za-z0-9\-\,\s]/’, ‘ ‘, $string); // Removes special chars keeping space and comma.
    return preg_replace(‘/-+/’, ‘-‘, $string); // Replaces multiple hyphens with single one.
    }
    If this solution works, a more skillful approach would be to use form validation.

    Just a little modification in regex to keep Accented Characters.

    $string = preg_replace(‘/[^A-Za-zà-ú0-9\-\,\s]/’, ‘ ‘, $string);
