Problem when trying to display image from database

[eluser]FabD[/eluser]
Problem solved.
What was wrong : the datatype of the variable was an OCI-Lob Object.
Not allowed to put it directly into a string of course :cheese:

so here is the code of the model's method

Code:

function getImage($Id)
{
   $Q = $this->db->query("SELECT MA_PHOTO FROM GERICO.REF_MARCHES WHERE MA_ID=".$Id);
   if ($Q->num_rows())       {
           $data = $Q->row_array();
           $data = $data['MA_PHOTO'];
           $Q->free_result();  
   }    
   $size = $data->size();        
   $ret = $data->read($size);    
   return (isset($ret)) ? $ret : '';
}
