            string path = Server.MapPath("file2.jpg");

            var buffer = File.ReadAllBytes(path);

            int size = 8192;
            byte[] data;
            int pos = 0;
            for (int i = 0; i < buffer.Length / size; i++)
            {
                data = new byte[size];
                pos = i * size;
                Array.Copy(buffer, pos, data, 0, data.Length);
                Response.OutputStream.Write(data, 0, data.Length);
                Response.OutputStream.Flush();
            }

            data = new byte[buffer.Length % size];
            Array.Copy(buffer, pos + size, data, 0, data.Length);
            Response.OutputStream.Write(data, 0, data.Length);
            Response.OutputStream.Flush();
