Solution with PIL:

import tkinter as tk
from PIL import Image, ImageTk


def work(progress=1):
    if progress > 300: # define the width by yourself
        return
    tmp_images = ImageTk.PhotoImage(progress_images.resize((progress, 10))) # the image size
    lb.image = tmp_images # keep reference
    lb["image"] = tmp_images # change the image
    root.add = root.after(100, work, progress+10) # define the amplitude by yourself


root = tk.Tk()

progress_images = Image.open("path.png")
lb = tk.Label(root, bg="black")
lb.pack(side="left")
work()

root.mainloop()
