Why won't this image display in tkinter? [duplicate]

Question

Here is my code:

from tkinter import *

class app(Tk):
    def __init__(self, *args, **kwargs):
        Tk.__init__(self, *args, **kwargs)
        image = PhotoImage(file="image.gif")
        Label(image=image).pack()

window = app()
window.mainloop()

When I run the above code, the image is not displayed. However, when I run the following code...

from tkinter import *

root = Tk()
image = PhotoImage(file="image.gif")
Label(image=image).pack()

root.mainloop()

...the image does show up. Why is this and how can I rectify it?

Replace:

image = PhotoImage(file="image.gif")
Label(image=image).pack()

with:

self.image = PhotoImage(file="image.gif")
Label(image=self.image).pack()

The image reference needs not to be garbage collected in order to be displayed.

This is exactly what I needed! Are there any other ways to solve the problem?

@MilanTom There can be a number of ways of solving. The key idea being keepinng the reference to the image object available in the scope which the image is shown. In the case above, it is the global scope.
