jQuery CSS Z-Index Change

I am having a problem getting my photoviewer to change photos when a link is clicked (live site http://ericnaff.com/web2/index-FILL-IN.html). I've looked everywhere for a solution and got nothing. Here's my HTML, then CSS, then my jQuery. I got the links to work but when you re-click, it won't change the image. Example- I click on a link and the photo changes to the right photo. If I try to go back to a photo by clicking, it doesn't work.

 <body>

<div id="imageWindow">
    <div class="imagePane firstPic"></div><!-- ends first -->
    <div class="imagePane secondPic"></div><!-- ends second -->
    <div class="imagePane thirdPic"></div><!-- ends third -->
    <div class="imagePane fourthPic"></div><!-- ends fourth -->

    <ul>
        <li class="firstPic">first-pic</li>
        <li class="secondPic">second-pic</li>
        <li class="thirdPic">third-pic</li>
        <li class="fourthPic">fourth-pic</li>
    </ul>

</div>

THE CSS

    #imageWindow {/* 1 CSS attribute */position:absolute 0px 0px;}

/* common image container and stacking */
    .imagePane {
        /* 4 CSS attributes */
        position:absolute;
        background-image: url(http://www.ericnaff.com/web2/images/park-    
                    sprite.jpg);
        width:450px;
        height:400px;
        }

/* these classes are used to determine the stacking order of the image container divs */
    .front {/* 1 CSS attribute */ z-index:1}
    .behind {/* 1 CSS attribute */ z-index:-1}

/* used to display a different picture in each container */             
    .firstPic {/* 1 CSS attribute */ background-position:0px 0;}
    .secondPic {/* 1 CSS attribute */background-position:450px 0;}
    .thirdPic {/* 1 CSS attribute */background-position:900px 0;}
    .fourthPic {/* 1 CSS attribute */background-position:1350px 0;}


/* used to style the list */
    ul {        
        /* 2 CSS attributes */
        width:75px;
        margin-left:450px;
    }

    li {
        /* 1 CSS attribute */
        list-style-type:none;           
    }

    li:hover {
        /* 2 CSS attributes */
        background-color:#999999;
        cursor:pointer;
    }

MY JQUERY-

    $(document).ready(function(){
    $('li.firstPic').click(function() {
                $('.firstPic').fadeIn().addClass('front');                  

            });

        $('li.secondPic').click(function() { 
                $('.secondPic').fadeIn().addClass('front');

            });

        $('li.thirdPic').click(function() {
                $('.thirdPic').fadeIn().addClass('front');

            });

        $('li.fourthPic').click(function() {
                $('.fourthPic').fadeIn().addClass('front');

            });

    });

Any ideas? I can't change the HTML and have to use the amount of CSS shown. I'm new to this and really confused. I was trying this solution-

$('.targetX').functionA('targetS').functionB('targetT');                    
$('tag.targetY').functionA('targetT').functionB('targetS');

I don't know how to get it to work though. Like I said, got the first part working, just can't get a link to work more than once. Thanks for any help/suggestions.

Each link adds a front class to its corresponding <div>, but doesn't remove any previously added ones.

For example, you can add this function on each click:

function resetClasses() {
    $('li').each(function() {
        $(this).removeClass('front');
    });
}

$(document).ready(function(){
    $('li.firstPic').click(function() {
                resetClasses();
                $('.firstPic').fadeIn().addClass('front');                  

            });

    $('li.secondPic').click(function() { 
            resetClasses();
            $('.secondPic').fadeIn().addClass('front');

        });

    $('li.thirdPic').click(function() {
            resetClasses();
            $('.thirdPic').fadeIn().addClass('front');

        });

    $('li.fourthPic').click(function() {
            resetClasses();
            $('.fourthPic').fadeIn().addClass('front');

        });

});

it's because before add front class, the previous front is not cleared yet. in your every click blocks add this $('.front').removeClass('.front');

but i think i can propose something like this :

$('.imagePane').click(function() {
   //get the second class name as the selector of li
   var picSelector = $(this).attr('class').split(" ")[1];

   $('.front').removeClass('front');
   $('li.'+picSelector).addClass('front');
});

im sorry i havent tested it yet, but i hope you got the idea..
