It looks like your src attribute is incorrect for you image.
<img class="pic" src="{{ STATIC_URL }}/static/img/foto.jpg" alt="foto"/>
should be
<img class="pic" src="{{ STATIC_URL }}img/foto.jpg" alt="foto"/>
Since STATIC_URL is already taking care of adding /static/ to your url. If you use the debugger tools in your browser and take a look at the src for that image you’ll probably see it saying “/static/static/img/foto.jpg” when it should be “/static/img/foto.jpg”

Also ensure you have collected the static image files by running:
python manange.py collectstatic
