Почему скрипт показывает только одну картинку?

Question

[Александр]

Всем привет!
Скрипт должен показать около 50 картинок а показывает одну потом пустой Label
Вот собственно скрипт

        for link in soup.find_all('img'):

            panel.config(width=w, height=h)
            panel.pack(fill="both", expand="no")

    application.mainloop()
