    get bitmap from image in website.

    i need to get bitmap data from image in current website.
    after i get bitmap handle, i want to save this bitmap.
    i got some code about it in several site, but it didnt work well.
    it got bitmap handle, but it didnt work to save file because of no correct bitmap data, i guess.
    can i get snippet code to fix it?
    best wishes

    I'm not quite sure what you mean by "getting a bitmap from a current website". If you want to download and save an image from a webserver, and you know the address of the image, you could do something along these lines:

    using System;
    using System.Net;
    using System.Drawing;
    namespace TestApplication
        class Program
            static void Main()
                // example
                DownloadImageAndSave("", "test.gif");
            static void DownloadImageAndSave(String image_address, String target_filename)
                WebRequest request = WebRequest.Create(image_address);
                WebResponse response = request.GetResponse();
                Bitmap bitmap = new Bitmap(response.GetResponseStream());
