Django 3 when sending a letter to mail, the images in the letter are not displayed, how to fix it?

Question

Django

subject = name_cinema
html_message = render_to_string('app_template/mail_template.html', context)
plain_message = strip_tags(html_message)
from_email = 'From <[email protected]>'
to = email

mail.send_mail(subject, plain_message, from_email, [to], html_message=html_message)

Layout mail_template.html, a problem with images, with the rest of the content, all the norms
are displayed only option 4, where we indicate a link to the image. {% load static %} connected

<img src="{% static 'img/1234.png' %}" alt="1">
<img src="{% static 'img/1.png' %}" alt="2">
<img src="../../1234.png" alt="3">

Answer 1

What is in STATIC_URL? '/static/'? That won't work. You need to either send images along with the email, or specify the full address in STATIC_URL a la ' https://domain.com/static/ '
