Can anyone tell me how to convert excel file into images using C# code and Microsoft.Office.Interop.Excel lib?

Using Microsoft.Office.Interop.Excel;             

string fileNameToProcess = @"C:\Users\infoobjects\Desktop\Test1 Single sheet.xlsx";
            //Start Excel and create a new document.
            xls.Application oExcel = new xls.Application();
            xls.Workbook wb = null;
            try
            {
                wb = oExcel.Workbooks.Open(fileNameToProcess.ToString(), false, false, Type.Missing, "", "", true, xls.XlPlatform.xlWindows, "", false, false, 0, false, true, 0);
                //wb.RefreshAll();
                xls.Sheets sheets = wb.Worksheets as xls.Sheets;
                for (int i = 1; i <= sheets.Count; i++)
                {
                    xls.Worksheet sheet = sheets[i];
                    //Following is used to find range with data
                    string startRange = "A1";
                    Microsoft.Office.Interop.Excel.Range endRange = sheet.Cells.SpecialCells(Microsoft.Office.Interop.Excel.XlCellType.xlCellTypeLastCell, Type.Missing);
                    xls.Range range = sheet.get_Range(startRange, endRange);
                    range.Rows.AutoFit();
                    range.Columns.AutoFit();
                    range.Copy();
                    System.Drawing.Image imgRange1 = Clipboard.GetImage();
                    imgRange1.Save(@"C:\Users\infoobjects\Desktop\" + "Test1" + i + ".Jpeg", System.Drawing.Imaging.ImageFormat.Jpeg);
                    Console.Write("Specified range converted to image successfully. Press Enter to continue.");
                    sheets[i].Delete();
                }

                wb.Save();
            }
            catch (Exception ex)
            {
                Console.WriteLine(ex.Message);
                //throw;
            }
            finally
            {
                wb.Close();
                oExcel.Quit();
                oExcel = null;
            }

            Console.ReadLine();

It will create a single image of the excel sheet based on the cell used in the sheet, but I want to create multiple images(If required) according to the A4 size sheet.
