views.py method:

def index(request):
    content = News.objects.all()

    for el in content:
        el.picture = '/' + str(el.picture).split('/')[-1]

    context = {
        'content' : content
    }

    return render(request, 'News.html', context)

Database:

Output:

HTML code:

<body> 
    <h1> News </h1>
    {% for el in content %}

      <h1><a href = "/news/{{el.pk}}"> {{ el.title }} </a></h1>
        
      <img src = "{% static 'pictures' %}{{el.picture}}", width="100", height="100">
      
      <p> {{el.content}} </p>
      <p> {{el.published}} </p>
      <a href = "/news/rubric№{{el.rubric.pk}}"> {{el.rubric}} </a>

    {% endfor %}
  </body>

I tried to do this, but then it just does not display the picture:

{% if el.picture != "" %}	
  <img src = "{% static 'pictures' %}{{el.picture}}", width="100", height="100">
{% endif %}

Also tried this:

{% if ".jpg" in el.picture %}	
  <img src = "{% static 'pictures' %}{{el.picture}}", width="100", height="100">
{% endif %}

For some reason, the constructions do not give out anything, the images do not appear at all

Who draws an image like that?
Throw it away, here it is

for el in content:
    el.picture = '/' + str(el.picture).split('/')[-1]

and do it in the template , and it's quite simple Threat and for /news/{{el.pk}} and other hrefs to kick too, and then send them to read the docks. {{ el.picture.url }}{% if el.picture %}
