How to mount a folder with pictures in a container without direct copying?

Question

Docker

Good day!
In this project, the task of Express is to give static content (pictures, of which 15 gigs).
In compose, I mount the build directory - there is an attachment for node. And there is also a public directory - it contains pictures.
But the problem is that there are only 20 gigs on the server, and when I start
docker build .
docker it starts copying all the pictures into the image and naturally the place runs out.
Attention, the question is: how can I configure compose so that I can give pictures to the outside and at the same time they are not copied into the inside of the image?
docker-compose.yml

version: '3'
services:
    web:
        image: docker-node-express-mongoapp
        build: ./
        working_dir: /usr/src/app/
        command: node index.js
        ports:
            - "3001:3001"
        volumes:
            - ./build:/usr/src/app
            - /usr/src/app/node_modules
        depends_on:
            - "mongo"
        
    mongo:
        image: "mongo"
        ports: 
            - "27017:27017"

    adminmongo:
        image: "mrvautin/adminmongo"
        ports:
            - "1234:1234"

Dockerfile

WORKDIR /usr/src/app
