Can verify this with PDO->mssql using 5.2.6 and Windows Server 2003. 

// Reproduction code:
$VIN = $_GET['VIN'];
	$imageUrl = $_GET['ImageUrl'];
	$sql_img = "SELECT VIN, Image, ImageUrl FROM ImagesDemo WHERE VIN =
:VIN AND ImageUrl =  :imageUrl";
	$result_img = Database::pdo_prepare_query($sql_img, array(':VIN' =>
$VIN, ':imageUrl' => $imageUrl));
	$result_img->bindColumn('Image', $lob, PDO::PARAM_LOB);
	$result_img->fetch(PDO::FETCH_BOUND);
	header("Content-type: image/pjpeg");
        var_dump($lob); // string(4096) + raw image data
	fpassthru($lob); // this call fails with 'supplied argument is not a
valid stream resource'
	echo $lob; // this call only spits out 4096 bytes, chopping the image
off

End result -- unable to use pdo for blobs.

I am using PHP 5.2.6 with MySQL 5.0.51b, and the problem is still
present.

Reproduce code:
---------------

$sql = "SELECT FileData FROM UserFile WHERE ID=?";

$stmt = $DB->prepare($sql);
$stmt->execute(array($FileID));
$stmt->bindColumn(1, $data, PDO::PARAM_LOB);
$stmt->fetch(PDO::FETCH_BOUND);
echo gettype($data);

Expected result:
----------------
resource

Actual result:
--------------
string
