C# Google API - Retrieve Google Contact Image

If we have a lot of contacts, it's very useful have the photo that help us to remember. 
The following code shows how to get google contact image

---

string qr = "YourContactUri".Replace("base", "full");

GDataCredentials Credentials = new GDataCredentials("yourMail@gmail.com", "yourPassword");

RequestSettings settings = new RequestSettings("appName", Credentials);

settings.UseSSL = true; //if you want to use ssl connection

ContactsRequest cr = new ContactsRequest(settings);

Contact contatto = cr.Retrieve<Contact>(new Uri(qr));

Image img = Image.FromStream(cr.Service.Query(contatto.PhotoUri));

pcb_foto.Image = img; //pcb_foto is a PictureBox put on the form

* if there is no image for the contact it need to manage the exception
