It seems like $path can also be of type false; however, parameter $filename of file_exists() does only seem to accept string, maybe add an additional type check?

It seems like $path can also be of type false; however, parameter $directory of mkdir() does only seem to accept string, maybe add an additional type check?

It seems like you do not handle an error condition for unlink(). This can introduce security issues, and is generally not recommended.

$model is of type yii\db\ActiveRecord, thus it always evaluated to true.

It seems like Yii::app->response can also be of type yii\web\Response. However, the property $response is declared as type yii\console\Response. Maybe add an additional type check?

        $response->getHeaders()->set('Content-Type', 'image/jpeg; charset=utf-8');

        Yii::$app->response->headers->set('Last-Modified', date("c", $model->created));
