read a list of images into sqlite 'wb'

import sqlite3
conn=sqlite3.connect('facial.db')
cursor = conn.cursor()

#=========================Insert Photos =======================
# Convert digital data to binary format
def convertToBinaryData(images):
    for images in Directory:
        with open(images, 'wb') as f:
            photo = f.read()
        name= "Pix"+1
       

    cursor.execute("""INSERT INTO faces_file (name, photo) VALUES (?,?) """,(name,photo)

Select allOpen in new window

convertToBinaryData(images)
conn.commit()
cursor.close()
conn.close()

Select allOpen in new window

photos are in the below directory and I want to read the list into my data base

Directory/
photo1.jpg
photo2.jpg
photo3.jpg

1. trying to read this list of Binary images into data base.... I can do it one at a time which is to slow

2. need to photos from Directory into a list to be encoded (Opencv)
