For Javascript gurus

Hi!

I would like some help at Javascript programming. I'm working on a page 'glossary of terms' (cca. 240 terms). It looks so: In left frame there's a description of term in the right there is/are corresponding picture(s). Pictures are not to be loaded all of them if there are more pictures related to a term. So I made a script which makes ONLY picture change if clicked on a corresponding link (under or over picture in the same frame). Page remains the same. However I would like a short description of a picture currently shown, which would change in a relation with the picture currently shown (means changing picture AND description at the same time -> at clicking corresponding link). I don't want to use textfields because they can't be graphically well designed.
Changing of pictures works well, I wonder only if someone knows, how to change description under picture with clicking on the same link WITHOUT changing whole page. Current HTML code is below.

Thank you.

HTML code:

<html>
<head>
<title>slike</title>

<body bgcolor="#000000">

<SCRIPT LANGUAGE="Javascript">

//definitions
var pict1 = 'pictures/chaos_1.jpg';
var descript1 = 'Picture 1: description';
var pict2 = 'pictures/catena_1.jpg';
var descript2 = 'Picture 2: description';
var pict3 = 'pictures/chasma_1.jpg';
var descript3 = 'Picture 3: description';

function picture1() { // function that shows picture 1 and description 1 AT THE SAME TIME
document.show.src = pict1;
document.atts.write = descript1; // ???
}

function picture2() {
document.show.src = pict2;
document.descr.src = descript2; // ???
}

function picture3() {
document.show.src = slika3;
document.atts.src = descript3; // ???
}

</SCRIPT>


<img src="pictures/catena_1.jpg" alt="chaos" width="230" height="230" hspace="0" vspace="0" border="0" align="top" name="show">
