Creating a pop up window

[Trapezium]

I'm a graphic designer and, until recently, I've never really had a use for HTML. My intentions are to create a (relatively) simple portfolio for myself, and I've got almost everything I need, but I'm having troubles with creating a pop up window.

I want a user to click on the thumbnail of an image, and for the full-size version to load in a new window.

I'm comfortable with the 'img src' and 'a href' tags, but I'm not certain on how to go about this, so any help on the matter is appreciated.

<a href="image.gif" target="_blank"><img src="image.gif"></a>

The href for the link will open the image file in your browser, and the target="_blank" opens it in a new window.
