protected void Page_Load(object sender, EventArgs e)
{

Response.ContentType = "image/jpeg";
Response.BinaryWrite(GetImageByte("http://cimg2.163.com/cnews/2007/10/29/200710290837338486c.jpg"));
}

/// <summary>

private byte[] GetImageByte(string Url)
{
WebResponse response = null;
Stream stream = null;

HttpWebRequest request = (HttpWebRequest)WebRequest.Create(Url);

response = request.GetResponse();
stream = response.GetResponseStream();

byte[] buffer = new byte[response.ContentLength];

stream.Read(buffer, 0, buffer.Length);
stream.Close();
return buffer;

}
