jqeury: facebook + coca-cola on facebook

Hi,

Does any one know how can I make programme like Coca-Cola on Facebook, where you can click on the images, and you will see a facebook popup, then you can comment on the image?

http://www.facebook.com/cocacola

Is it a javascript default code from facebook itself or a developer has to create it?

Can I use jquery on facebook by the way or any way to get around to using jquery on facebook?

Thanks!
Lau
