查看05featuredemo.inc.php或PHPExcel documentation等示例，了解如何将图片添加到工作表中。

$objDrawing = new PHPExcel_Worksheet_Drawing();
$objDrawing->setName('PHPExcel logo');
$objDrawing->setDescription('PHPExcel logo');
$objDrawing->setPath('./images/phpexcel_logo.gif');
$objDrawing->setHeight(36);
$objDrawing->setCoordinates('D24');
$objDrawing->setOffsetX(10);
$objDrawing->setWorksheet($objPHPExcel->getActiveSheet());
