Javascript Passing value from a popup window to its parent window

Question

I'm new in javascript and I'm stuck here. Let's say I have a parent window and it has an input field as well as a button that opens a popup window. This popup window contains Images. I just need to copy image URL to that input in the parent window when I click on any image on the popup window. Any help please. Thanks

Edit:

This is my javascript code on the popup window

<script type="text/javascript">
function clicked(address) {
    window.parent.document.getElementById('copy_img').value = address.src;

}
</script>

HTML

<input type="text" name="copy_img" id="copy_img" size="133" />
<img border="0" onclick="clicked(this)" src="images/1.jpg" width="135" height="46">
<img border="0" onclick="clicked(this)" src="images/2.jpg" width="128" height="48">
<img border="0" onclick="clicked(this)" src="images/3.jpg" width="305" height="44">

Parent Window HTML Code

<input type="text" name="copy_img" id="copy_img" />

I Just Can't get it to work

Answer 1

I finally figured it out Use window.opener

window.opener.document.getElementById('archiveimages').value = address.src;
