    Download an image from a URL

    Hey everyone,

    I'm having problems downloading an image from in internet location.

    I've tried 2 methods:

    Code:
    request = (HttpWebRequest)WebRequest.Create(newUrl);
    request.Method = "GET";
    
    response = (HttpWebResponse)request.GetResponse();
    Stream imageStream = response.GetResponseStream();
    Bitmap bmp = new Bitmap(imageStream);
    bmp.Save(GetFileName(url));
    and

    Code:
    WebClient client = new WebClient();                                
    client.DownloadFile(newUrl, fileName);
    The first method throws an exception in the Bitmap constructor "Invalid parameter used." The second method saves the picture, put it is in the wrong format or something, because it can't be viewed, and is only 917 bytes on disk (actual image is 84000 bytes.)

    Any ideas or other methods that can be used to download images?

    Thanks!

    PHP Code:
    System.Net.WebClient client = new System.Net.WebClient();
     
    client.DownloadFile"http://www.cprogramming.com/cprog.gif""cprog.gif"); 
    This saves the cprog image just fine. Make sure you have internet access and your connection or the server does not go down while downloading

    She was so Blonde, she spent 20 minutes looking at the orange juice can because it said "Concentrate."

    When in doubt, read the FAQ.
    Then ask a smart question.

    As it turns out, there was just something whack with the image I was trying to download. All other images worked fine. Thanks for the reply!
