Facebook Graph API - Retrieve photo - Unsupported get request -

i testing facebook graph api via explorer. managed feed using me/home. however, want details uploaded pictures. read on other posts, have re-run query using object_id in post object.

this works public images. whenever seek on friend's photo, get:

{ "error": { "message": "unsupported request. please read graph api documentation @ https://developers.facebook.com/docs/graph-api", "type": "graphmethodexception", "code": 100 } }

one of them photo of wife. checked privacy setting, far can see, doesn't block 3rd party api's. how can photo details of posts api returns in me/home?

i know doesn't work photo's unique permissions (so e.g. tags in them), tested photo's shared person's friends. tested 10, none of them work. how possible?
