You can use send_file to return a file from flask. For an image, use mimetype='image/gif'. Something like this:

from flask import send_file

@app.route('/get_image')
def get_image():
    # your code here
    return send_file(filename, mimetype='image/gif')

Hope this helps. Good luck.

Please have a separate question for that to avoid the risk of getting closed for "too broad" – Harshal Parekh Oct 19 '19 at 18:34
