using a javascript funtion with php

[Matthew Robinson]

im crap with javascript, im not so hot with php, but anyway here's what
ive got

<script type="text/javascript">
var lay1=0
var lay2=0
function showpicture() {
lay2=0
if (lay1%2==0) {
document.getElementById("L1").style.display="block " } else {
document.getElementById("L1").style.display="none" }
document.getElementById("L2").style.display="none" lay1++
}
\
</script>

.....and inside a loop (looping through every item in a mysql database
<a href="#" onclick="showpicture(); return false">Show A
Picture Of This Product</a>
<div id="L1" style="display:none">
<a href="<?php echo ($picturepath); ?>"
target="LargeImage">
<img src="<?php echo ($picturepath); ?>"
height=200 alt='Image Of Product'> <font
size=2><br>Click The Image To See It Full
Size In A New Window</font>
</a>
</div>

$picture path is fine, because it worked before i had the javascript and i
just had <img src="<?php echo ($picturepath); ?>" height=200 alt='Image Of
Product'>

but that script only works the first time i click the "Show A Picture Of
This Product" hyperlink. if i press the same link further down, it doesn't
do anything, but the first time i click it on the page, it works for that
item (if that made any sence)

im trying to put a hyperlink (or a button, but hyperlink is easier) to
show a pictures for products only when the specific link is clicked. that
way it makes it possible to use scaled down images (so the man im writing
it for only has to upload one fullsize picture rather than two because he
wanted it hassle free)
does anybody have any idea how i could make it work how i want to?

thanks in advancee.

So this is a js question, not a php question. So please address a js group.
