I just thought someone could take the old code and adapt it for this forum software. This is the old code:
.cForumRow.ipsDataItem[data-forumid="1013"]{
background-image: url('https://i.imgur.com/GdVi7Jq.png') !important;
background-size: cover !important;
background-position: bottom center !important;
min-height: 262px;
}
