[Python] Error while converting PIL image to Tkinter image

I'm trying to rotate an image using Pillow:

img = Image.open("./assets/aircraftCarrier/aircraftCarrier0.gif")

img = img.rotate(270)


This rotates the image but when I try to save it Pillow doesn't seem to recognise the file type, even if I put the format type when saving it:

img.save("./tempData/img", "GIF")


It comes up with a file with a blank extension

Now this doesn't really matter as long as tkinter can recognise it with PhotoImage, but that doesn't seem to work either:

img = PhotoImage(img)

label = Label(root, image=img)
label.pack()


I get this error message:

TypeError: __str__ returned non-string (type Image)


I'm not really sure what I've done wrong or if I need to do more processing with Pillow.

Help would be greatly appreciated,

Josh


Full code:

import tkinter as tk
from tkinter import *
import tkinter
from PIL import Image

root = tk.Tk()
root.title("Test")


img = Image.open("./assets/aircraftCarrier/aircraftCarrier0.gif")

img = img.rotate(270)

img.save("./tempData/img", "GIF")

img = PhotoImage(img)

label = Label(root, image=img)
label.pack()

root.mainloop()
