If you are getting the FacebookID just generate the image URL

 <img src="https://graph.facebook.com/FacebookIDOrUserName/picture"/>

http://developers.facebook.com/docs/reference/api/

If you need to download the image:

Image image = null;
string URL = "https://graph.facebook.com/FacebookIDOrUserName/picture";

HttpWebRequest req = (System.Net.HttpWebRequest)HttpWebRequest.Create(URL);
req.AllowWriteStreamBuffering = true;
req.Timeout = 20000;

WebResponse resp = req.GetResponse();
System.IO.Stream stream = resp.GetResponseStream();

image = Image.FromStream(stream);

resp.Close();
