Tkinter does not natively support image formats such as JPEG and PNG. The PhotoImage class of Tkinter can read images only in the GIF and PGM/PPM formats. Although there are workarounds, such as using the ImageTk and Image submodules from the PIL module, it would have been better if Tkinter natively supported popular image formats.
