Обновление изображения в Custom Tkinter

Я делаю простое приложение погоды в Custom Tkinter, используя API OpenWeather, и у меня возникают проблемы с обновлением значка погоды, когда пользователь вводит другой город из списка. Я все еще работаю над приложением, извините за грязный код.

import requests
from customtkinter import *
from PIL import Image


app = CTk()
app.title('Turtle')
app.geometry('1000x500')





c_img = CTkImage(light_image=Image.open('cloudy.jpg'),size=(100, 100))
msg_label = CTkLabel(app, text = "", text_color='Blue', font=('Arial', 25, 'bold'))
temp_label = CTkLabel(app, text = "", text_color='Blue', font=('Arial', 25, 'bold'))
condition_label = CTkLabel(app, text = "", text_color='Blue', font=('Arial', 25, 'bold'))
wind_label = CTkLabel(app, text = "", text_color='Blue', font=('Arial', 25, 'bold'))
alert_label = CTkLabel(app, text = "", text_color='Blue', font=('Arial', 25, 'bold'))



filename1 = "cloudy.jpg"




name_entry = CTkEntry(app, font=('Arial', 25, 'bold'), corner_radius=32)

ecity = ""




def update_weather(event):
 
 filename1 = 'cloudy.jpg'
 ecity = ""
 ecity = name_entry.get()

     print(f"Weather for {cityname}")

     print(data)
    
     msg_label.configure(text=f"Weather for {cityname}: ", font=('Arial', 20, 'bold'))

 if 'rain' in condition.lower():

 image_label = CTkLabel(app, image=c_img, text = "")
 image_label.pack()

name_entry.bind('<Return>', lambda event: update_weather(event))



update_weather(True)
msg_label.pack()
temp_label.pack()
condition_label.pack()
wind_label.pack()
alert_label.pack()
name_entry.pack()

app.mainloop()

Вместо этого я попробовал использовать CTkLabel:

c_img = CTkImage(light_image=Image.open('cloudy.jpg'),size=(100, 100))

###Code###

c_img.configure(light_image = Image.open(filename1))

Он обновился, но только один раз, и распечатал изображение в окно.
