Haven’t been programming in JS for a while.
Now, I have following thing:

<html>
<head>
<script language="JavaScript">
   function enlarge()
   {
   window.close();
   }
</script>
</head>
<body>
<img src="addresstomyimg.png" onClick="enlarge()" />
</body>
</html>

(it’s very simplified, as, in fact, I have WordPress platform with custom JS modifications etc, but in general, this is the idea).

I don’t understand why it’s not working.

    JavaScript cant close the window unless it opened the window.

    In your function, replace window.close() with alert('here') and you’ll see the function works fine.

    If you want your function to close a window, first open one: 

    <html>
<head>
<script type="text/javascript">
    var popup;

    function closewin()
    {
        popup.close();
    }
    function openwin()
    {
        popup = window.open('http://www.google.com');
    }
</script>
</head>
<body>
    <img src="addresstomyimg.png" onclick="openwin()" /> Click to open, then come back here
    <br><br>
    <img src="addresstomyimg.png" onclick="closewin()" /> Click to close
</body>
</html>
