string uploadFolder = Server.MapPath(Request.ApplicationPath + "images/");
FileUpload1.SaveAs(uploadFolder + FileUpload1.FileName);
ResizeSettings resizeCropSettings = new ResizeSettings("width=200&height=200&format=jpg&crop=auto");
string fileName = Path.Combine(uploadFolder, System.Guid.NewGuid().ToString());
fileName = ImageBuilder.Current.Build(uploadFolder + FileUpload1.FileName, fileName, resizeCropSettings, false, true);
