You can use a database to store pictures and other small images in a database table. Such picture files can be processed more efficiently on a file server.

However, when image data is stored in a binary field, it can only be accessed by applications that stream raw picture data to and from that field.

The MongoDB GridFS specification is a viable option for storing fairly large files in MongoDB. It ensures that the files are broken down into manageable bits and saved in the database.

This article explains the process of saving and retrieving binary files in MongoDB.

GridFS in MongoDB

GridFS is a standard for storing and retrieving files that are larger than the 16 MB limit set by BSON. GridFS splits files into parts, or chunks, and stores each part separately rather than as a single document.

Store a metadata JSON document for each item in Couchbase, along with at most a small thumbnail.

The document contains the information about that object in your application that you need and references a purpose-built object store such as S3, a file system, or HDFS. So you'll have the best of both worlds.

In this MongoDB tutorial, the issue of storing images in MongoDB database is discussed in detail. Also, you will learn about different ways to save images and retrieve images from MongoDB database efficiently.

Storing images in MongoDB using GridFS

You can store images in a MongoDB database by creating a schema using Mongoose. The schema is model.jsdefined by creating a file.

Data type Bufferis used to store images in the database form of array.

There are three ways to store images:

Since large files are difficult for end users to access, storing binary files in a database makes it easier to distribute across numerous sites. It is worth noting that before saving photos to a database, you should consider its benefits.

Storing images in MongoDB using Python

This section will discuss how to store images in MongoDB using Python.

There are two libraries you can use for this:

pip3 install pymongo

You can now use the library after installing it. But first, import the library, connect to the server to use MongoDB in Python, and set up a database to store photos.

from pymongo import MongoClient

connection = MongoClient("localhost", 27017)

database = connection['DB_NAME']

MongoDB runs by default on port 27017. You can DB_NAMEspecify any name for the database in .

The GridFS library stores photos in a MongoDB database in the following stages.

import gridfs
#Create an object of GridFs for the above database.
fs = gridfs.GridFS(database)

#Define an image object with the location.
file = "C:/Users/user/Pictures/dog.jpeg"

with open(file, 'rb') as f:
    contents = f.read()

fs.put(contents, filename="file")

The above code shows how to save photos in a MongoDB database using Python.
