public static void UploadPhoto(string albumId, string
originalFileName, byte[] photo, UploadPhotoCallback callback)
{
string Username = "mailmugu";
string AuthToken = "R3wxDZxHfixvDaQzkpAJXICY";
try
{
var url = string.Format("http://picasaweb.google.com/
data/feed/api/user/{0}/albumid/{1}", Username, albumId);
var request = WebRequest.Create(new Uri(url)) as
HttpWebRequest;
//request.ContentType = HttpFormPost.ImageJpeg;
//request.Method = HttpMethods.Post;
request.ContentType = "image/jpeg";
request.Method = "POST";
request.Headers[HttpRequestHeader.Authorization] =
"GoogleLogin auth=" + AuthToken;
request.BeginGetRequestStream(new
AsyncCallback(UploadGetRequestCallback),
new UploadRequestState
{
Request =
request,
Callback =
callback,
Photo = photo,

}
catch (Exception e)

Console.WriteLine(e);
//throw new
MyException(MyResources.ErrorUploadingPhotoMessage, e);
}
}
private static void UploadGetRequestCallback(IAsyncResult ar)
{
try
{
var state = (UploadRequestState)ar.AsyncState;
HttpWebRequest request = state.Request;
// End the operation
var stream = request.EndGetRequestStream(ar);
stream.Write(state.Photo, 0, state.Photo.Length);
stream.Close();
request.BeginGetResponse(UploadGetResponseCallback,
state);
}
catch (Exception e)
{
//throw new
MyException(MyResources.ErrorUploadingPhotoMessage, e);
}
}
private static void UploadGetResponseCallback(IAsyncResult ar)
{
UploadRequestState state = null;
try
{
state = (UploadRequestState)ar.AsyncState;
HttpWebRequest request = state.Request;
// End the operation
HttpWebResponse response =
(HttpWebResponse)request.EndGetResponse(ar);
if (response != null)
{
response.Close();
}
if (state.Callback != null)
{
MessageBox.Show("Uploaded Sucessfully");
//state.Callback(true,
MyResources.PhotosUploadedMessage);
}
}
catch (Exception e)
