이미지/레이블이 PIL/Python 3.6과 함께 표시되지 않음

Question

레이블 위젯에 이미지를 삽입하려고합니다. show() 함수를 사용하면 이미지가 성공적으로로드됩니다. 어떤 이유로 이미지가 GUI에 표시되지 않습니다. 나는 앱의 전체 배경을 보여주기 위해 노력했지만, GUI의 나머지 부분으로 이동하는 방법을 파악하는 동안 한 프레임에 표시하는 것이 허용 될 수 있습니다. 다음은이 매우 일반적인 문제입니다 화면 출력 샷 코드

Answer 1

입니다 다음. PhotoImage 객체에 대한 참조를 유지해야합니다.

background_image = Image.open('client-bg.jpg') 
background_image = ImageTk.PhotoImage(background_image) 
background_label = Label(top_mid, image=background_image) 
background_label.image_ref = background_image # keep the reference! 

그렇지 않으면 이미지가 가비지 수집됩니다.
