I do not want all the photos to appear when I upload my web

I'm working on this template that uses the MixItUp plugin. When I load the page I do not want all the photos to appear, only the menu.

<div class="work-filter wow fadeInRight animated" data-wow-duration="500ms">
                    <ul class="text-center">

                        <li><a href="javascript:;" data-filter="all" class="active filter">All</a></li>
                        <li><a href="javascript:;" data-filter=".branding" class="filter">Almacenamiento &amp; Despacho</a></li>
                        <li><a href="javascript:;" data-filter=".web" class="filter">Puntos de Venta &amp; Inventario</a></li>
                        <li><a href="javascript:;" data-filter=".logo-design" class="filter">Transporte &amp; Distribución</a></li>
                        <li><a href="javascript:;" data-filter=".tres" class="filter">Última Milla &amp; Tracking</a></li>
                        <li><a href="javascript:;" data-filter=".dos" class="filter">Gestión Móvil</a></li>
                    </ul>
                </div>
