I added the following lines in my settings.py file:
STATIC_URL = '/static/' STATICFILES_DIR = [ os.path.join(BASE_DIR,"static"), ] STATIC_ROOT = os.path.join(BASE_DIR,"static") Then I edited my HTML file to use {% load static %} and <img src="{% static 'static/myapp/images/ABC.png' %}" alt="">, but still I am not able to see the ABC.png pic on my webpage. Can someone please help?
Screenshots of .py files: 
The issus is that you are incorrectly requesting the asset, use {% static 'myapp/images/ABC.png' %} instead. I suppose that you have the following structure in your app:
myapp static myapp images ABC.png templetes views.py ... As you can see, is not necessary to add the name of your statics directory. The path is relative to the static folder of any of your apps in your project.
STATIC_URL = '/static/' should work. You should have the static folder inside your apps instead your project, you can have one static folder by each app and the path you use in the templates is relative to your static folders. try running python manage.py collectstatic
