How to embed images in a symfony mail?

So I designed an email template for my reset-password system.In the email templates, there are Images (logo).

I placed those images inside a folder called Email_Images and that folder is placed inside the Public folder!

First, I tried to link the images using Asset() twig Function like this:

<img alt="logo 1" src="{{asset('Email_Images/1.png')}}" /><img alt="logo 2" src="{{asset('Email_Images/2.jpg')}}" />

But none of them works. So I tried to get the image in the controller and send it to the template, like this :

 $email = (new TemplatedEmail())        ->from(new Address('myEmail@gmail.com', 'My Subject'))        ->to($user->getEmail())        ->subject('Your password reset request');        $img= $email ->embed(fopen('Email_Images/1.jpg', 'r'), 'img');        $email->htmlTemplate('reset_password/email.html.twig')        ->context(['resetToken' => $resetToken,'img' => $img,'tokenLifetime' => $this->resetPasswordHelper->getTokenLifetime(),        ]);

In the template I did

<img alt="logo 1" src="{{ img }}" />

and I get this error :

An exception has been thrown during the rendering of a template("Catchable Fatal Error: Object of classSymfony\Bridge\Twig\Mime\TemplatedEmail could not be converted tostring").

What is the right way to add/embed an image in an Email?
