Image not showing in tkinter button-CodePudding

I created a button with an image in Tkinter, but the image isn't showing, i can just see a blank space in the button. Maybe my OS is the problem. I have Linux Mint 21 Xfce Edition.

from tkinter import ttk
from tkinter import filedialog
from tkinter import messagebox
from tkinter import dialog
from tkinter import *
from PIL import ImageTk, Image
from modules import fonts, buttons
import shutil
import os
virusscan_win = Tk()
        virusscan_win.title("Virus scan")
        virusscan_win.geometry('400x200 60 60')
        virusscan_win.configure(background="white")
        Message(text="The virus scanner gives them the ability to scan files, folders or their system for viruses and remove threats automatically.", width=250, font=fonts.sansserif_small, background = "white").place(x=10, y=10)
        safe_image=PhotoImage(file='./media/button.png')
        Button(master=virusscan_win, image=safe_image, text="Scan file").place(x=10, y=90)

Can anyone explain, what was wrong with my code? I already checked, is the file in the correct folder. the debugger also shows nothing.

Tkinter is notorious for aggressively garbage collecting image references, which leads to them being destroyed before the UI gets drawn. Something like this should work for getting an image onto a Button

from PIL import Image, ImageTk
from pathlib import Path


img_path = Path('C:/<path>/<to>/media/button.png')  # use the full path to your img file
with Image.open(img_path) as img: # open the image file
    img_tk = ImageTk.PhotoImage(img)  # get the image as a Tk object
button = Button(virusscan_win, image=img_tk)  # add image to button

Note that if your image is the wrong size for your button, you can resize it like so

img_tk = ImageTk.PhotoImage(img.resize(32, 32))  # or whatever size you need
