[Plugin: Shadowbox JS] New window opening when watching post

Hi guys, i have a question (maybe a few) to you about the Shadowbox-JS wordpress plugin : )

The thing what i need is to open a new window with my other site, when someone is watching one particular post of my blog.
For instance I’ve got a notebook tests in my blog post, and when someone enter this post I want to show him the detailed specifics of every computer from the other site (I’ve got direct link ofc) – I heard, that the shadowbox is good to this task, so i installed this plugin to my blog, but now i can’t do what i want to do 🙂

Any help would be appreciated! Thanks!
