Мой составной текст не обновляется поверх моего изображения Tkinter

Question

Это мой первый опыт использования Tkinter и Python. Я хочу запустить серию из четырех изображений в цикле. Пользователь взаимодействует с интерфейсом, щелкая каждое изображение. У моего 4-го изображения есть сложный текст, который появляется на нем. Я не могу удалить этот составной текст, когда программа запустится снова.

Это строка кода с посвященными соединение текста:

displayButton.configure(image=photo4, text = sc , compound=CENTER, fg = 'Black',  font='Verdana 30 bold', command=callback, wraplength=250, justify=CENTER) 

currentpicture=4 

Это код, который настраивает displayButton, но он не работает.

if currentpicture==4: 
displayButton.configure(image=photo1) 
currentpicture=1 

Может ли кто-нибудь помочь?

Это полный код:

right_top = 0 
left_top = 0

left_bottom = 0 

# defines the function for the callback button 
# declares the screen and currentpicture as global variables 
# checks the current picture and change it :)

Если добавить текст на кнопку, он будет оставаться там до тех пор, пока не будет изменена. Попробуйте следующее:

displayButton.configure(image=photo1, text='')
