Problems with "New Window Tutorial"

I am having problems trying to get this to work:

I have tried plugging in my own information throughout the tutorial, but I have not been able to get it to work. What I am trying to do is have multiple buttons (all different) open a new window with a contained size (essentially no chrome) so that pics that they are linked to will be able to be viewed full size. I hope I explained that well enough for someone to help me out. If there’s a better way to do this please let me know.

Thanks for you time.
