By default, images are uploaded to the data directory of the app itself. To switch to another provider like MinIO, first configure minio to image uploads. Then, use the following configuration in /app/data/config.json:

    "imageUploadType": "minio",
    "s3bucket": "codimd-images",
    "minio": {
        "accessKey": "MINIO_ACCESS_KEY",
        "secretKey": "MINIO_SECRET_KEY",
        "endPoint": "minio.domain.com",
        "secure": true,
        "port": 443
    }
