How do they do this?

http://img710.imageshack.us/img710/6222/howdotheydothis.png

and make it go to this:

http://www.chelick.net/LikeIt/?id=21

Do u know the LIKE BUTTON, is a new option from facebook, it's like SHARE but with other style,
1. creat a new html page
2. go to http://developers.facebook.com/docs/reference/plugins/like
add all the page informations there
3. past the html code in your page and upload it to your host

That's what i know about this
but i think about the website there is a script, i think is easy to code it

Sorry for my bad english
