import time
from tkinter import *
tk = Tk()
w = 500
h = 500
canvas = Canvas(tk, width=w, height=h)
canvas.pack()

my_image = PhotoImage(file='C:\\WinPython-64bit-3.5.3.0Qt5\\notebooks\\stani.gif')
my_img = canvas.create_image(0,0, anchor=NW, image=my_image)


for x in range(0,60):
    canvas.move(my_img, 5, 0)
    tk.update()
    time.sleep(0.05)

for x in range(0,60):
    canvas.move(my_img, 0, 5)
    tk.update()
    time.sleep(0.05)
    
for x in range(0,60):
    canvas.move(my_img, -5, 0)
    tk.update()
    time.sleep(0.05)

for x in range(0,60):
    canvas.move(my_img, 0, -5)
