Cómo get todas las fotos cuando el usuario carga 2 o más en Facebook para iOS

{ comments = { count = 0; }; "created_time" = "2013-01-23T06:12:43+0000"; from = { id = 1171029418; name = "Ilse Anhy"; }; icon = "https://fbstatic-a.akamaihd.net/rsrc.php/v2/yz/r/StEh3RhPvjk.gif"; id = "1171029418_10200426347839190"; link = "https://www.facebook.com/photo.php?fbid=10200426378279951&set=a.3604514069432.2168112.1171029418&type=1&relevant_count=2"; "object_id" = 10200426378279951; picture = "https://fbcdn-photos-a.akamaihd.net/hphotos-ak-ash4/265145_10200426378279951_1504367216_s.jpg"; privacy = { value = ""; }; "status_type" = "added_photos"; story = "Ilse Anhy added 2 new photos."; "story_tags" = { 0 = ( { id = 1171029418; length = 9; name = "Ilse Anhy"; offset = 0; type = user; } ); }; type = photo; "updated_time" = "2013-01-23T06:12:43+0000"; } 

En el object "historia" dice "Ilse Anhy agregó 2 fotos nuevas". En el object "image" solo da una reference a una sola foto. ¿Cómo podría recuperar la otra foto?
