Here is the relevant code to my problem.  I know it's a lot, and if you don't feel like reading it I understand.

 

<style type="text/css">
#slideshow {
width:635px;
height:455px;
z-index:1;
}
#main {
background-image:url('1.jpg');
width:635px;
height:360px;
z-index:2;
}
#placehold {
background-color:transparent;
height:300px;
z-index:3;
}
.placeholdthumb {
background-color:transparent;
height:49px;
z-index:5;
}
.captionthumb {
height:16px;
background-color:black;
color:white;
text-align:center;
font-family:Helvetica, Arial, sans-serif;
font-size:14px;
opacity:0.7;
filter:alpha(opacity=70);
cursor:pointer;
}
#caption {
background-image:url('captbg.gif');
background-repeat:no-repeat;
color:white;
font-size:16px;
font-weight:bold;
opacity:0.8;
filter:alpha(opacity=80);

padding-left:11px;
}
#roll {

line-height:11px;
width:635px;
margin-left:auto;
margin-right:auto;
background-image:url('rollbg.png');
height:95px;
z-index:2;
}

As it stands now, the captions on highlighted pictures simply get larger in an instant.  However, this is not good enough for my brother (my non-paying client...).  I've tried all manner of increment the height and width of the placediv and captdiv elements with setInterval and setTimeout, but to no avail.  This is basically a shameless ask for help.  Could someone show me what I need to do in order to have the captions slide up/down?
