Pop up windows that close on clicks

I was wondering how I would I can make pop up windows that close when you click on them like http://www.minitruckinweb.com/archives/features/0502_feature02.shtml

cause I have a bunch of show pics,so also keep in mind I have like 12 pics per page alot,and will need to do it to all the pics.

Just make the image a link, and use a javascript event:

<a href="#" onclick="javascript:window.close()"><img src="yourimage.jpg" border="0"></a>

That's all they're doing.

Still doesnt work for me. It keeps on saying do you want to close the window and the thumbnail wont work. Do I need to add something in the header or something?

if the window is opened by a javascript pop up, then that message will not appear. It will only appear if its a main window with all the Menus and all..
