Why Doesn't My Tkinter Image Appear When Created Inside a Class Function?

Why does Tkinter image not show up if created in a function within a class?

In Tkinter, creating an image within a function will not display the image. This behavior arises because the variable that references the image, denoted as photo in the example code, is a local variable that is garbage collected once the function completes its execution.

To address this issue, it is necessary to store a reference to the image instance as an attribute of the class. This can be achieved using a line similar to:

self.photo = tkinter.PhotoImage(...)

where self refers to the instance of the Test class. This ensures that the variable photo remains available throughout the lifetime of the class, allowing the image to be displayed.
