Essentially, I'd like to have pictrs delete all of the images that aren't uploaded by my users, because my storage usage was going through the roof, so I just disabled the proxying of images. Here is my config:

x-logging: &default-logging
  driver: "json-file"
  options:
    max-size: "50m"
    max-file: "4"

    restart: always
    logging: *default-logging
