Embedded Resource = Встроенные данные

Наша программа требует наличия текстуры "texture4.jpg" и в конструкторе производится попытка поиска текстуры по адресу "http://gems.novikov.de/resources/texture4.jpg".
Проблема: Если это не сработает - программа стартует без текстуры.
Решение: Встройте "texture4.jpg" про грамму:
1. В Solution Explorer кликните правой кнопкой на проект texture1. В контекстном меню выберите Add - Add Existing Item....В диалоговом окне выберите Image Files (*.bmp, ... ). и найдите и загрузите файл текстуры на вашем компьютере. Элемент "texture4.jpg" появится в проекте. В свойствах этого элемента "Properties"поменяйте свойство Build Action с Content на Embedded Resource.
2. Сотрите в конструкторе public Form1() следующий блок:
try { //Delete this inner try-catch clause if you have no Internet connection running.
   String s = "http://www.miszalok.de/Images/tiger.bmp";
   System.Net.WebRequest webreq = System.Net.WebRequest.Create( s );
   System.Net.WebResponse webres = webreq.GetResponse();
   System.IO.Stream stream = webres.GetResponseStream();
   bmp = (Bitmap)Image.FromStream( stream );
} catch {}; 

и замените этот код на строку:
bmp = new Bitmap( typeof( Form1 ), "texture1.texture4.jpg" ); //read the embedded resource

Теперь после построения нового texture1.exe - программа содержит собственную начальную текстуру.
Плюс: "texture4.jpg" при старте всегда на месте независимо от ресурса в интернете..
Минус: Размер texture1.exe увеличился на размер файла текстуры texture4.jpg.
