Lightbox Gallery Img link

Hi, Currently version 4.3.1 - lightbox gallery img link not pointing to asset folder if page in subfolder.

Example:

<div class="row photos">
            <div class="col-sm-6 col-md-4 col-lg-3 item"><a href="assets/img/...."><img src="../assets/img/...." /><p></p></a></div>

noticed ref to "asset/img/....." instead of "../asset/img/....."]1

Missing = "../"

Thus image not popping up in lightbox when click.

Thank you Edward
