            {
                var reader = new PdfReader(inputPdfStream);
                var stamper = new PdfStamper(reader, outputPdfStream);
                PdfContentByte pdfContentByte = null;

                int c = reader.NumberOfPages;
                string fnmae = "";
                iTextSharp.text.Image image = null;

                for (int i = 1; i <= c; i++)
                {
                    fnmae = (i % 2==0) ? "1.jpg" : "6.jpg";
                    image = iTextSharp.text.Image.GetInstance(fnmae);
                    pdfContentByte = stamper.GetOverContent(i);
                    image.ScaleToFit(100, 100);
                    image.SetAbsolutePosition(100, 100);
                    pdfContentByte.AddImage(image);
                }


                stamper.Close();
            }

Now what I want to ask is it is possible that I create the images in the beginning and use its reference in the pages in which I want to insert the specific image.
