webcrawler for images

[sagey]

i've tried using the code that tewl kindly provided and it seems to fail when trying to get the image using the web client

		private void Crawl()
		{
			//get source 
			string source = "";
			HttpWebRequest hwr = (HttpWebRequest)WebRequest.Create("http://intranet");
			HttpWebResponse hwrsp = (HttpWebResponse)hwr.GetResponse();
			Stream s = hwrsp.GetResponseStream();
			StreamReader sr = new StreamReader(s);
			source += sr.ReadToEnd();
			sr.Close();
			s.Close();
	
			//MessageBox.Show(source);
			
			//get image stuff
			WebClient dl = new WebClient();
			string flink = "", fpath = "";
			string[] f = null;
			Match mMatch = Regex.Match(source, "<img([^>])src=[',\"](.*?)[',\"].*?>", RegexOptions.IgnoreCase);
			while (mMatch.Success)
			{
				flink = "http://intranet" + mMatch.Groups[2].ToString();
				f = Regex.Split(flink,"/");
				fpath = @"D:\Watermark\WebCrawler\CrawledImages\" + f[f.Length - 1];
				dl.DownloadFile(flink,fpath);
				mMatch = mMatch.NextMatch();
			}		
		}

I'm trying to test this against my works intranet homr page, i don't know whether thats got anything to do with it?
here is the output from vs:
