Everything isinside this function public void DownloadPicture() { int nNumErrors=0; WebClient client=new WebClient(); client.Credentials = CredentialCache.DefaultCredentials; while(!StopDownloading) { try { byte[] oFileData=client.DownloadData(m_sURL); if(oFileData.Length>20) { string sFileName=m_sID + "_" + DateTime.Now.ToString("yyyyMMdd hh mm ss") + ".jpg"; Bitmap.FromStream(new MemoryStream(oFileData)).Save(m_sFolderLocation + sFileName,ImageFormat.Jpeg); } } catch(SystemException ex) { nNumErrors++;} } }

I know it's a long time scince you posted this, but look at the HttpWebRequest and HttpWebResonse Classes, there very easy to use, but don't use the Stream Reader to get the data, either use the stream directly or use the BinaryStreamReader. enjoy.

You can use HTTP or FTP protocols for this purpose. See the Internet section of this site. There are some samples available. Also see The HttpWebClient class and its DownloadFile method (I think)
