HtmlDocument doc = new HtmlDocument(); doc.Load("myfile.htm"); foreach(HtmlNode node in doc.DocumentElement.SelectNodes("//img[@src"]) { HtmlAttribute att = node["src"]; att.Value = "//your new image path"; } doc.Save("myfile.htm"); Guna Jayakumars, if this helps please login to Mark As Answer. \| Alert Moderator
