How to use httpwebrequest to pull image from website to local file

I'm trying to use a local c# app to pull some images off a website to files on my local machine. I'm using the code listed below. I've tried both ASCII encoding and UTF8 encoding but the final file is not an correct. Does anyone see what I'm doing wrong? The url is active and correct and show the image just fine when I put the address in my browser.

    private void button1_Click(object sender, EventArgs e)
    {
        HttpWebRequest lxRequest = (HttpWebRequest)WebRequest.Create("http://www.productimageswebsite.com/images/stock_jpgs/34891.jpg");

        // returned values are returned as a stream, then read into a string
        String lsResponse = string.Empty;
        HttpWebResponse lxResponse = (HttpWebResponse)lxRequest.GetResponse();
        using (StreamReader lxResponseStream = new StreamReader(lxResponse.GetResponseStream()))
        {
            lsResponse = lxResponseStream.ReadToEnd();
            lxResponseStream.Close();
        }

        byte[] lnByte = System.Text.UTF8Encoding.UTF8.GetBytes(lsResponse);

        System.IO.FileStream lxFS = new FileStream("34891.jpg", FileMode.Create);
        lxFS.Write(lnByte, 0, lnByte.Length);
        lxFS.Close();

        MessageBox.Show("done");
    }

c# image file httpwebrequest

Edit Report

nice image :D

try using the following code:

you needed to use a BinaryReader, 'cause an image file is binary data and thus not encoded in UTF or ASCII

edit: using'ified

HttpWebRequest lxRequest = (HttpWebRequest)WebRequest.Create(
"http://www.productimageswebsite.com/images/stock_jpgs/34891.jpg");

// returned values are returned as a stream, then read into a string
String lsResponse = string.Empty;
using (HttpWebResponse lxResponse = (HttpWebResponse)lxRequest.GetResponse()){
   using (BinaryReader reader = new BinaryReader(lxResponse.GetResponseStream())) {
      Byte[] lnByte = reader.ReadBytes(1 * 1024 * 1024 * 10);
      using (FileStream lxFS = new FileStream("34891.jpg", FileMode.Create)) {
          lxFS.Write(lnByte, 0, lnByte.Length);
      }
   }
}
MessageBox.Show("done");
