Trying to trying to select images from a database and insert them into a Treeview

Question

I am trying to select images from a database with other info and insert them into a Treeview, and this Treevire has to be shown in a notebook,

I have tried the following code:

from PIL import ImageTk, Image
from io import BytesIO
from tkinter import filedialog
from tkinter.filedialog import askopenfile
import sqlite3
class Cardealer():
    def __init__(self):
        self.root = root
        
# calling dashboad_checks so its showing the treeview on the root notebook
        self.dashboard_checks()

def dashboard_checks(self):
        self.con = sqlite3.connect('car dealership.db')
        self.cursorObj = self.con.cursor()

        self.buying_checks_row = self.cursorObj.execute(
            'SELECT checkpic, buyername, carmake, checknum, checkvalue, checkdate FROM cars_selling_checksonly')
        self.buying_checks_output = self.cursorObj.fetchall()

        self.checkslist_buying_img = []
        for record in self.buying_checks_output:
            checks_buying_img = ImageTk.PhotoImage(date=record[0])
            self.Dashboardcheck_buying_tree.insert("", 
            END,image=checks_buying_img,values=record[1:])
            self.checkslist_buying_img.append(checks_buying_img)

        self.con.commit()

    def selling_filedialogscheckonepic(self):
        global filename, img, images
        f_types = [("png", "*.png"), ("jpg", "*.jpg"), ("Allfile", "*.*")]
        filename = filedialog.askopenfilename(filetypes=f_types)
        img = Image.open(filename)
        img = img.resize((700, 270), Image.ANTIALIAS)
        img = ImageTk.PhotoImage(img)
        self.selling_checkimagelabel.place(x=20, y=60)
        self.selling_check_fob = open(filename, 'rb')
        self.selling_check_fob = self.selling_check_fob.read()
        self.selling_check_fob = (self.selling_check_fob)

I got the following error:

Traceback (most recent call last):
  File "C:\Users\user\Desktop\thecardealer(new version)\main.py", line 3271, in <module>
    x = Cardealer()

    return ImageMode.getmode(mode).basemode
  File "C:\Users\user\AppData\Local\Programs\Python\Python310\lib\site-packages\PIL\ImageMode.py", line 74, in getmode
    return _modes[mode]
KeyError: None

AttributeError: 'PhotoImage' object has no attribute '_PhotoImage__photo'

Process finished with exit code 1

I would appreciate any help as I am a new programmer and still learning.
