If it is fine to keep the board name, you could start with something like:
#board_1 .board_name:after {
background-image: url(http://turtlebackzoo.com/wp-content/uploads/2013/01/wolf1.jpg);
display: block;
width: 100%;
height: 150px;
content: "";
background-repeat: no-repeat;
}
Then you can add all the bells and whistles you want.
