Buttons

How can I click on a button, and have an image open up in the pop-up (lightbox)? 

Here is an example: http://www.nhd-prague68.com/czechoslovakia.html  (scroll down a bit, the three buttons)

Thank you so much in advance!

It looks like they're using custom code to make that happen, @agagagwaka.
