Onmouseover pop-up image

[Mutley]

I'm trying to write a really basic script. So when your mouse pointer goes over the image it creates a pop-up (or DIV) which ever is easist of the same image.

This is for part of a news page, each article is partly shown, to view it all you need to goto the articles page but I want people to see the full image by rolling over it and not just half of it.

So something like:
<img src="image.jpg"> onmouseover('makepopup<img src="image.jpg" />') onmouseout()
... or something, I know nothing about Javascript, when your mouse pointer rolls off the image I would like the pop-up to close.

Thanks.

Best script I've ever found for this is at http://www.walterzorn.com/tooltip/tooltip_e.htm
