This is the answer that works for placing an image in a specific location. `

    using (PdfStamper stamper = new PdfStamper(new PdfReader(fromFilePath), File.Create("toFilePath")))
            {
                AcroFields.FieldPosition fieldPosition = stamper.AcroFields.GetFieldPositions("btn1")[0];

                PushbuttonField imageField = new PushbuttonField(stamper.Writer, fieldPosition.position, "btn1Replaced");
                imageField.Layout = PushbuttonField.LAYOUT_ICON_ONLY;
                imageField.Image = iTextSharp.text.Image.GetInstance(ImageLocationPath);
                imageField.ScaleIcon = PushbuttonField.SCALE_ICON_ALWAYS;
                imageField.ProportionalIcon = false;
                imageField.Options = BaseField.READ_ONLY;

                stamper.AcroFields.RemoveField("btn1");
                stamper.AddAnnotation(imageField.Field, fieldPosition.page);

                stamper.Close();
            }
