Answer 1

it is easy. Crawl page, find url of the image with regex or jQuery for example and pass it as string to method below:

private void GetImage(string url)
        {
                    Stream imageStream = new WebClient().OpenRead(url);
                    Image img = Image.FromStream(imageStream);
                    img.Save(@"C:\MyImage.jpg");
        }
