For example Google RSS keeps all images within a summury.

So u can extract it by this code:

List<RssFeedItem> rssItems = new List<RssFeedItem>();
                    Stream stream = e.Result;
                    XmlReader response = XmlReader.Create(stream);
                    SyndicationFeed feeds = SyndicationFeed.Load(response);
                    foreach (SyndicationItem f in feeds.Items)
                    {
                        RssFeedItem rssItem = new RssFeedItem();

                        rssItem.Description = f.Summary.Text;

 const string rx =  @"(?<=img\s+src\=[\x27\x22])(?<Url>[^\x27\x22]*)(?=[\x27\x22])"; 
                        foreach (Match m in Regex.Matches(f.Summary.Text, rx, RegexOptions.IgnoreCase | RegexOptions.Multiline))
                        {
                            string src = m.Groups[1].Value;
                            if (src.StartsWith("//")) // Google RSS has it
                            {
                                src = src.Replace("//", "http://");
                            }

                            rssItem.ImageLinks.Add(src);
                        }
