How can I upload an image using FtpWebRequest?

I have been working at building a feature for a client that will enable them to upload images from www.site1.com, storing the image URL to the database and storing the images to a file on www.site2.com/images. I have managed to upload a file to the target location, but when I try to open and view the image, it is said to contain errors. I've never really had to work with images, so I'm at a loss.

This is the method used to upload the files:

public static void UpLoadImage(Stream image, string target)
{
FtpWebRequest req = (FtpWebRequest)WebRequest.Create("ftp://www.site2.com/images/" + target);
req.UseBinary = true;
req.Method = WebRequestMethods.Ftp.UploadFile;
req.Credentials = new NetworkCredential("myUser", "myPass");
StreamReader rdr = new StreamReader(image);
byte[] fileData = Encoding.UTF8.GetBytes(rdr.ReadToEnd());

rdr.Close();
req.ContentLength = fileData.Length;
Stream reqStream = req.GetRequestStream();
reqStream.Write(fileData, 0, fileData.Length);
reqStream.Close();
}


This is where the method is called from (image1 is an HttpPostedFileBase):

myObject.UpLoadImage(image1.InputStream, storedTL.ID + "-1.png");


If there is a way that I can make this code work, or if there is an all around better way to do this, please help.

Answer

StreamReader is meant to read text.

Change:

StreamReader rdr = new StreamReader(image);
byte[] fileData = Encoding.UTF8.GetBytes(rdr.ReadToEnd());

to

byte[] fileData = File.ReadAllBytes(image);
