PHPExcel more than one image in a cell - php

Question

I need to create an excel document with only 2 col. The first one will contain multiple images 150px large and the seconde one will contain a web code. For some reason only one image is added and the file appears to be currupted. Not sure what i am doing wrong ...
<?php
include("../../init.php");
if (is_numeric($_GET[groupe])){
define( 'PCLZIP_TEMPORARY_DIR', $_CONFIG['upload']['root'].'/cache' );
// filename for download
$groupe = mysql_query("SELECT * FROM photographe_groupe WHERE id='$_GET[groupe]'");
$records = "Groupe - $groupe[nom].xlsx";
header('Content-type: application/vnd.openxmlformats-officedocument.spreadsheetml.sheet');
header('Content-Disposition:inline;filename='.$records);
$workbook = new PHPExcel;
$sheet = $workbook->getActiveSheet();
$i=0;
$select = mysql_query("SELECT * FROM photographe_images WHERE sid='$_GET[groupe]' group by `paire`");
while($photo = mysql_fetch_array($select)){
// Table header
if ($i=="1"){
$sheet->setCellValue("A1",'Photo(s)');
$sheet->setCellValue('B1','Code Web');
$i++;
}
// Set images in col 1
$select1 = mysql_query("SELECT * FROM photographe_images WHERE paire='$photo[paire]'");
while($photo1 = mysql_fetch_array($select1)){
$objDrawing = new PHPExcel_Worksheet_Drawing();
$objDrawing->setName($photo1[img]);
$objDrawing->setDescription($photo1[img]);
$objDrawing->setWorksheet($workbook->getActiveSheet());
$objDrawing->setPath($_CONFIG['upload']['root'].'/userfiles/photos/'.$photo1[img]);
$objDrawing->setWidth(150);
$objDrawing->setCoordinates('A'.$i);
}
// Set web code in col 2
$sheet->setCellValue("B$i",$photo[code_web]);
$i++;
}
}
$workbook->getActiveSheet()->getRowDimension(1)->setRowHeight(-1);
$writer = new PHPExcel_Writer_Excel2007($workbook);
PHPExcel_Settings::setZipClass(PHPExcel_Settings::PCLZIP);
$writer->save('php://output');
?>

Just a few points to note before I try taking a look at your file:
The first point to note here is that Excel doesn't store images in cells, it "overlays" images, and doesn't particularly care where cell boundaries occur, so an image can be a fixed size irrespective of how many cells it overlays
When you specify a coordinate for a image, you're relating the top-left corner of that image to be placed at the top-left corner of that cell.... where the bottom and/or right corner of the image lies isn't determined by the cells at all. Setting the row height or column width to autosize will not be affected by the image in any way, because the image is overlaid, not a content of the cell
You can, offset the image from the top-left corner of the related cell by using the Drawing object's setOffsetX() and setOffsetY() methods.
You can link more than one image to be placed relative to the same cell's top-left corner using different offset values so they don't overlap, but you need to work out the offsets from the size of the images
