MySQL Update Statement + File Upload

Question

Greetings! Been staring at this all day and can't seem to figure out why my update statement fails to update the field 'image_filename':

  $fileName = $_FILES['image_filename'];
 if($fileName["name"] <> ""){
  $imageFile = $fileName['name']; 
  $destination = "../../../../assets/resources/images/".$fileName['name'];
  move_uploaded_file($fileName['name'], $destination);
 } 


  $updateSQL = sprintf("UPDATE content SET image_filename='$imageFile' WHERE id=%s",
     GetSQLValueString($_POST['resource_id'], "int"));

mysql_select_db($database_conn_talent, $conn_talent); $Result1 = mysql_query($updateSQL, $conn_talent) or die(mysql_error());

Can a SQL pro tell me what I"m missing? Much thanks in advance for your feedback!

You appear to be building a query, but never executing it. Also, Drupal'll handle all the sprintfing for you, if you let it.

$query = "UPDATE content SET image_filename='$imageFile' WHERE id=%i";
db_query($query, $_POST['resource_id']);
