Python – Update Image Dynamically

The update function

# dynamically update image
def update_image():
global photo
# new image
imgPath = "/Users/Shared/Images/image1.png"
doesImageExist=os.path.isfile(imgPath)
if doesImageExist == False:
# default image
imgPath = "/Users/Shared/Images/default/image1.png"
photo = ImageTk.PhotoImage(Image.open(imgPath))
photoBox.config(image=photo)

Part of my widget or form

root = tk.Tk()
root.geometry("350x300")# X Y
root.resizable(0,0)
root.title("Window Title")

root.attributes('-topmost', True)

imgPath = "/Users/Shared/Images/image1.png"
photo = ImageTk.PhotoImage(Image.open(imgPath))
photoBox = tk.Label(root, image = photo)
photoBox.pack()

root.mainloop()

Call the image update

root.after(1000, update_image)
