$objPHPExcel = new PHPExcel();

$objDrawing = new PHPExcel_Worksheet_Drawing();

对呀！
你的 $objDrawing = new PHPExcel_Worksheet_Drawing(); 在循环外面
而 $objDrawing->setWorksheet($objPHPExcel->getActiveSheet()); 在循环里面
你如何能保证 $objDrawing = new PHPExcel_Worksheet_Drawing(); 只被这行一次呢？
虽然是套在条件分支中的，你有如何能保证条件只成立一次呢？

你只需把 $objDrawing = new PHPExcel_Worksheet_Drawing(); 放到循环里面，一切都解决了
