How can I change this?

Hey all, my site is in my signature and I need some help changing the Browse Categorys list. I want to Change each of the five category links with my own picture I've made the same size as the boxes.

Here's the category code

#middle {
	width: 920px;
	background:#fff;
	float:right;
	padding:10px;
	margin:10px 0;
	}

.category {
	width:164px;
	float:left;
	border-top:8px solid #333;
	margin:0px;
	padding:5px 10px 10px 10px;
	background:#fff;
	}

.category p {
	margin:0;
	}

#cat-1, #cat-3, #cat-5  {border-top:8px solid #333333;}
#cat-2, #cat-4 {border-top:8px solid #3c78a7;}

.category span.cat_title, #front-popular h3, #front-list .cat_title, #archive .cat_title {
	text-transform:lowercase;
	margin:0;
	font-weight:bold;
	font-size:1.5em;
	letter-spacing:-0.05em;
	}

#front-popular h3 {
	color:#fff;
	}

.category a {
	color:#333;
	display:block;
	background:none;
	}

.category a:hover {
	background:none;
	color:#fff;
	text-decoration:none;
	}

#cat-1:hover, #cat-3:hover, #cat-5:hover {background:#333333; color:#fff; }
#cat-2:hover, #cat-4:hover {background:#3c78a7; color:#fff; }
#cat-1:hover a, #cat-3:hover a, #cat-5:hover a {background:#333333; color:#fff; }
#cat-2:hover a, #cat-4:hover a {background:#3c78a7; color:#fff; }

If yes then PM me I'll help you!

 

Not really. I just want to use my own image as a Category link, in the same place that the links already are
