Below is my code. I'm trying to get image results from google for my given key words.
Getting an issue near
responseStream.Length as 'responseStream.Length' threw an exception of type 'System.NotSupportedException'
responseStream.Position as 'responseStream.Position' threw an exception of type 'System.NotSupportedException'

C#

string requestUri = string.Format("http://images.google.com/images?q={0}&ndsp={1}&start={2}&filter={3}&safe={4}",query, RESULTS_PER_QUERY.ToString(),(startPosition + i).ToString(), (filterSimilarResults) ? "1" : "0", safeSearchStr);

                HttpWebRequest request = (HttpWebRequest)WebRequest.Create(requestUri);
                string resultPage = string.Empty;
                using (HttpWebResponse httpWebResponse = (HttpWebResponse)request.GetResponse())
                {
                    using (Stream responseStream = httpWebResponse.GetResponseStream())
                    {
                        using (StreamReader reader = new StreamReader(responseStream))
                        {
                            resultPage = reader.ReadToEnd();
                        }
                    }
                }

I think you are referring some old resource for fetching images using google image search, time to time google search parameters are changing. I have done below simple test with minimum parameters and able to receive page content.

C#

string url = string.Format("https://www.google.com/search?site=imghp&tbm=isch&q={0}", "codeproject");
HttpWebRequest request =
(HttpWebRequest)WebRequest.Create(url);
string resultPage = string.Empty;
using (HttpWebResponse httpWebResponse =
            (HttpWebResponse)request.GetResponse())
{
    using (Stream responseStream =
                httpWebResponse.GetResponseStream())
    {
        using (StreamReader reader =
                    new StreamReader(responseStream))
        {
            resultPage = reader.ReadToEnd();
        }
    }
}
