I have a Django app with my images on Google Cloud Storage, but I want to use just one image on the local folders

This is my code:

Settings.py

GS_CREDENTIALS = service_account.Credentials.from_service_account_info(credentials_dict)
DEFAULT_FILE_STORAGE = 'storages.backends.gcloud.GoogleCloudStorage'
GS_PROJECT_ID = 'projectid'
GS_BUCKET_NAME = 'bucketname'
STATICFILES_STORAGE='storages.backends.gcloud.GoogleCloudStorage'

HTML:

<img src="{% static 'img/testimg.png' %}" alt="">

I want to search just for one image, how can I do this?

I tried removing Staticfiles_storage line, then django searched all the images on the local folders, instead of just one
