Laravel 5: sending multiple mails with the same image embedded causes "Swift_IoException: Unable to open file" error

In Laravel's email, an image becomes inaccessible if it's embedded multiple times.

To clarify the point, here is a piece of the code...

    //For Recipient A
    Mail::send('email', $data, function ($message) use ($emailA) {
        $message->from(env('MAIL_ADDRESS'), env('MAIL_TITLE'));
        $message->to($emailA);
    });

    //For Recipient B
    $data['flag'] = true;
    Mail::send('email', $data, function ($message) use ($emailB) {
        $message->from(env('MAIL_ADDRESS'), 'Title for recipient B');
        $message->to($emailB);
    });

    //In the 'email' view....
    @if(!empty($flag))
    <div>Flag is true</div>
    @endif
    <img src="">

Error message is - Swift_IoException: Unable to open file for reading [http://ift.tt/2waHez2]

Recipient A received the email with the image.jpg, but the email wasn't sent to Recipient B. Because Recipient A gets the email with the image file, the image file itself must be available. Then, why Swift is unable to open it?

Any advice will be appreciated!
