title: PHP Excel reader image/file not found when trying to insert an image into an excel file
body: <p>I am trying to export an excel sheet/file. Inside the file are product data and I am trying to insert the products' image along with other product data for each product. However everytime I run my export code I get an error which is something like, <code>File http://path_to_file/image.jpg not found!</code>. I am using <code>CakePHP</code> by the way. My code for exporting the excel sheet goes like this:</p>
  
  <pre><code>$objDrawing = new PHPExcel_Worksheet_Drawing();
  $objDrawing-&gt;setName('Water_Level');
  $objDrawing-&gt;setDescription('Water_Level');
  $objDrawing-&gt;setPath(''.PATH_TO_IMAGES.'image.jpg');
  $objDrawing-&gt;setHeight(20);
  $objDrawing-&gt;setCoordinates('A1');
  $objDrawing-&gt;setWorksheet($excel-&gt;getActiveSheet());
  </code></pre>
  
  <p>Is there something wrong with my code? Thanks.</p>
