HTML - Click to close

Hi,

Is there any way to add some html code which will close a pop-up window with a picture in it?

This is the code of a page I have which is popped up trough flash:

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
<title>Winter Picture 1</title>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1">
</head>
<body background="../../temp/pattern.gif">
<center><img src="../../../Digital/22.)Sneeuw-Tuin/Web/IMG_1.jpg" width="800" height="600"></center> 
</body>
</html>

Is there any way to add some code to this, so when you click the image for instance, the window closes again?

Thanks and cheers
