                        FtpWebRequest reqFTP;

Here are sample code for Download file from FTP Server

Uri url = new Uri("ftp://ftp.demo.com/Image1.jpg");
if (url.Scheme == Uri.UriSchemeFtp)
{
    FtpWebRequest objRequest = (FtpWebRequest)FtpWebRequest.Create(url);
    //Set credentials if required else comment this Credential code
    NetworkCredential objCredential = new NetworkCredential("FTPUserName", "FTPPassword");
    objRequest.Credentials = objCredential;
    objRequest.Method = WebRequestMethods.Ftp.DownloadFile;
    FtpWebResponse objResponse = (FtpWebResponse)objRequest.GetResponse();
    StreamReader objReader = new StreamReader(objResponse.GetResponseStream());
    byte[] buffer = new byte[16 * 1024];
    int len = 0;
    FileStream objFS = new FileStream(Server.MapPath("Image1.jpg"), FileMode.Create, FileAccess.Write, FileShare.Read);
    while ((len = objReader.BaseStream.Read(buffer, 0, buffer.Length)) != 0)
    {
        objFS.Write(buffer, 0, len);
    }
    objFS.Close();
    objResponse.Close();
}

You need to get the data (the image) into a byte array and then send that. The FtpWebRequest.GetResponse documentation example shows the basics, although it's appending a file. Everything else is relevant to what you're doing (you'd replace the append with upload file).

To get the image into a byte array, you can write:

byte[] imageBuffer = File.ReadAllBytes(imageFileName);

Everything else should be very similar to the documentation example.
