I can retrieve facebook cover source and offset_y from graph api for example -
https://graph.facebook.com/Inna
I get this -
\"cover\": {
Yes i actually found the answer myself. The offset that facebook sends is in percentage!
The following worked perfectly -
FB.api(artist, function (data) { $('.ed-cover img').attr('src', data.cover.source) .css("top", (-1 * data.cover.offset_y) + '%'); });
