Faking a Graphical Link

Then you need to work on your CSS. You need to change the display of your anchor tags to block for this trick to work in Mozilla. Otherwise I think the CSS is pretty straight forward:

	  a.menu{
		color:#ffffff;
		font-family:verdana;
		font-size:11px; 
		font-weight:bold;
		text-decoration:none;
		line-height: 30px;
		width:120px;
		height:30px;
		position:absolute;
		background-image: url("up.jpg");
		background-repeat: no-repeat;
		text-align: center;
                display: block;
	}
	a.menu:hover {
		color:#000000;
		background-image: url("down.jpg");

	}

Nothing too complicated there. You need to set the width and height to the dimensions of the image you are using as a background.
