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
