Could someone please help me into turning this: .changepicture .img { width: 185px; height:185px; display:block; background-image: url('img/duck.png'); }

.changepicture .img:hover { background-image: url('img/peng.png'); } into a simpler template? I don't know how to explain it properly, But here is kind of what I want it to.  If someone could please help me, I'd really appreciate it. :)
