Popup sized by Image Size

[gportella]

My problem is: I have a lot of pictures in my site and i have a menu with this images in a reduced scale. All that i wanna is to when the visitor click in this images a popup window opens and show the image in it real size.

How i do that kind of thing?

Thanks.
