outlook cannot download pictures from yii2 controller action

Question

I am sending HTML emails containing images, the src attribute for those images is an URL to a yii2 controller action that outputs the image content.

Images are shown if I open my email on the browser, my problem is with outlook that can not download and show my images.

Here is my action to output the image:

public function actionImage($img_name) {
        $filepath = Yii::getAlias('@webroot')."/media/files/$img_name";
        if (file_exists($filepath))
        {
            $mime = \yii\helpers\BaseFileHelper::getMimeType($filepath);

            header('Content-Type: '.$mime);
            header('Content-Disposition: attachment; filename="' . $img_name. '"');
            header('Content-Length: ' . filesize($filepath));

            // Render the file
            readfile($filepath);

            exit(0);
        }
        else
        {
           die('Media Not Found!');
        }
    }

first i would check my server access files and see if outlook is even bothering to make the request; if it is the issue is with what is being returned, so check the Apache headers; if its not the issue is with the url. — , May 29 '18 at 23:17
I checked, action is getting called when I try to download pictures on Outlook, Outlook is making a request per image. — anwar, May 30 '18 at 01:30
then make sure request returns the 'right' headers. its likely to be fussier than a browser — , May 30 '18 at 01:33

The function sendFile from yii2 response helped to solve the problem.

This worked and Outlook downloaded the images.

public function actionImage($img_name) {
        $filepath = Yii::getAlias('@webroot')."/media/files/$img_name";
        if (file_exists($filepath))
        {
            $mime = \yii\helpers\BaseFileHelper::getMimeType($filepath);

            \Yii::$app->response->sendFile($filepath);
            \Yii::$app->response->send();

            exit(0);
        }
        else
        {
           die('Media Not Found!');
        }
    }
