Having trouble using photo for background

[blakefindlay]

Just wondering what I am doing wrong. I have a photo named overlander_sports.jpg in the newb folder which is the name of the project. I can't seem to get it as a background.

from tkinter import *
import datetime
from tkinter import messagebox

root = Tk()
#Date and Time

C = Canvas(root, bg="blue", height=250, width=300)
filename = PhotoImage(file="C:\\Users\\blake\PycharmProjects\\newb\\overlander_sports.jpg")

background_label = Label(root, image=overlander_sports.jpg)
background_label.place(x=0, y=0, relwidth=1, relheight=1)

C.pack()
