string FilePath = @"..\..\..\Sample Files\";
string FileName = FilePath + "Image Markers.xlsx";
//Get the image data.
byte[]imageData = File.ReadAllBytes(FilePath + "Aspose.Cells.png");
//Create a datatable.
DataTable t = new DataTable("Table1");
//Add a column to save pictures.
DataColumn dc = t.Columns.Add("Picture");
//Set its data type.
dc.DataType = typeof(object);
//Add a new new record to it.
DataRow row = t.NewRow();
row[0]= imageData;
t.Rows.Add(row);
//Add another record (having picture) to it.
//imageData = File.ReadAllBytes(FilePath + "Desert.jpg");
//row = t.NewRow();
//row[0]= imageData;
//t.Rows.Add(row);
//Create WorkbookDesigner object.
WorkbookDesigner designer = new WorkbookDesigner();
//Open the temple Excel file.
designer.Workbook = new Workbook(FileName);
//Set the datasource.
designer.SetDataSource(t);
//Process the markers.
designer.Process();
