Yii2 sending email. Can't insert a .png image into the email body?

Question

Email

$res=Yii::$app->mailer->compose('layouts/message_info', ['text' => $text,'logo' => Yii::getAlias('@img').'/logo. jpg']);
I pass the path to the image into the view and in the form:
use yii\swiftmailer\Message;
$message = new Message;

I insert it, but the letter comes with an empty tag
. If the $logo variable is printed, then - string (48) "cid: [email protected]"
Tell me what I'm wrong
