.WikiaActivityModule.module { background-image: url("http://i.imgur.com/7ZNXnQj.png") !important; background-size:100% !important; }

.HotSpotsModule.module, .FollowedPagesModule.module { background: url("http://img4.wikia.nocookie.net/__cb20140529201113/neptunia/images/5/50/Wiki-background"); background-size:100%; }
