I'm not sure if I'm posting this in the right place, sorry if I didn't.

Anyways, I have some thumbnails on my page that link to a pop up window with an html file showing the entire image.

I've been a few sites with this kind of setup, and in the the pop up window there is a link to "close this window."

What would be the code to use to get that link?

<a href="javascript:self.close()">Close Window</a>
