FB Like Integrated – Strange Icon and Text for the website in Timeline (FB)

Hey!
My website http://lukasesch.com/ is finally online.

I also added a facebook like function for the website (top corner).
On the facebook timeline, everytime someone likes it, appears the Link to the website AND a icon from my second last picture as well as a piece of text from my widget.

How can I set an FB icon and text for the website?
Thanks!
