Simple Facebook integration

Hello everyone, I want to make something very simple with the Facebook
JS
SDK: The user would go to a picture’s page on my app, click on a button,
then a pop-up would appear the user would login to Facebook and
authorize
the app then a message would be posted to his wall. I don’t want to
make
the user login in my app with Facebook, only want to post to his wall.
Any
suggestion on what to do?

Thanks!

You might just want to see what Facebook’s ‘like’ button does, but I
don’t
know how this is a Rails questions. Unless you use Rails to fill in the
parameter for the like button’s message that Facebook then uses to fill
in
the user’s wall with…

Yes, but Facebook Like doesn’t do what I need. I really need to post to
the
user’s wall.

Any other suggestions?
