First of all, you add the identifier of the uploaded image when you add it. eg
var client = new FacebookClient(Access_Token); JsonObject jsonResponse = client.Get("me/feed") as JsonObject; string feed_ID = string.Empty; foreach (var account in (JsonArray)jsonResponse["data"]) { feed_ID = (string)(((JsonObject)account)["id"]); goto Next; } Next: { };
let's say you have the id of your last snapshot with 12345123_5488224848 support now you want to update this picture. write the following code.
var client2 = new FacebookClient(Access_Token); clientS.Post("12345123_5488224848/likes");
done. after that check the condition of the photo.
