The class PhotoImage of tkinter is used to display images in Labels, Buttons, Canvas and Text.
The method _show() is an internal method of the object Image; It should not be called directly. A tip for this is that it starts with a _; is an internal method, a detail of implementation that is called by the PIL itself. 
If you are creating a method _show, is trying to modify the way PIL will display images, but you should not call this method directly.
To finish follow an example of class use PhotoImage, where an image is inserted inside a text area tkinter.Text:
img = """

Always give preference to sharing the code instead of an image, this enables other people to use your code as a basis, makes it easy to point out fixes and adaptations. Also, could you be a little clearer? I really don’t understand what you want.
