I want to add a like button to every pic, so people can like the pics in the app tab and don't need to go to the wall. How can i do this? I tried the regular way, but got warned:The page at {address} could not be reached.

The problem is how can I add like button to facebook page's photos? How to link like button to such address http://www.facebook.com/photo.php?fbid=227099727304169&set=a.227058580641617.78517.227053027308839&type=1?
