Te duci in custom la tema respectiva si adaugi / modifici:

#ipsLayout_header {
    background: #17191b;
        background-position-x: 0%;
        background-position-y: 0%;
        background-repeat: repeat;
        background-image: none;
        background-size: auto;
    background-repeat: no-repeat;
    background-position: 50% 25%;
    background-size: cover;
    /* aici pui ce imagine vrei, sa fie securizata cu "https" */
    background-image: url("http://sfwallpaper.com/images/nikola-tesla-wallpaper-11.jpg");
    /* marire dimensiune sus */
    padding-top: 100px;
}
