gridfs_example.py

import bottle
import pymongo
import gridfs

from bottle import response

# this is the handler for the default path of the web server

@bottle.route('/img/<filename>')
def show_img(filename):

    # connect to mongoDB
    connection = pymongo.MongoClient('localhost', 27017)

    # attach to test database
    db = connection.test

    fs = gridfs.GridFS(db, "images")
    fsout = fs.get_last_version(filename=filename)
    response.content_type = 'image/jpeg'

    return fsout

bottle.run(host='localhost', port=8082, reloader=True)

Please note that you have to insert your files like this:

grid = gridfs.GridFS(db, "images")
fin = open(file_used, "r")

_id = grid.put(fin, filename=file_used)
fin.close()
