Rotate jpeg images based on exif data

[taravasya]

Hello! Thanks for your greate code! Im just want to propose some little new feature(as it sayed in issue title). For this just need to add one more argument to your function:
$exifrotation = false
and then after existing string(at line 91):

imagecopyresampled($image_resized, $image, 0, 0, $cropWidth, $cropHeight, $final_width, $final_height, $width_old - 2 * $cropWidth, $height_old - 2 * $cropHeight);

add liitle peace of code:

	if ($exifrotation && $info[2] == IMAGETYPE_JPEG) {
	$exif = exif_read_data($file);
        if (!empty($exif['Orientation'])) {
            switch ($exif['Orientation']) {
                case 3:
                    $image_resized = imagerotate($image_resized, 180, 0);
                    break;

                case 6:
                    $image_resized  = imagerotate($image_resized, -90, 0);
                    break;

                case 8:
                    $image_resized  = imagerotate($image_resized, 90, 0);
                    break;
            }
        }
	}

Sorry what Im not crete new PR(its because I`m not so oriented for this things ))) )
And.. also may be this code not good enough for new PR.
Anyway thank you! ))

I've tried the code and nothing happens.

Is the code dependent on a specific image library like ImageMagick or GD?
(My server has GD installed).

My bad; I got a file with wrong EXIF Orientation in the test file - I've tried another file with correct EXIF data and now the image rotate.

does this script depend on any Library like GD ?

I came here looking for ability to resize images without relying on any Library
