Why photoimages don't exist?

Question

I will show a reduced portion of the code that gives me a problem.

_tkinter.TclError: image \"pyimageN\" doesn\'t exist - where N stays for 1, 2, 3, etc

Answer 1

I solved myself the problem :

The second class I defined was the problem cause it used another root window, alias Tk(). An equivalent to the normal Tk() window is the Toplevel() that is the same as a root but hasn't its own interpreter context.

Shortly, to solve the problem I had to change the first line of the init() method of the EditorWindow class from

        self.Eenu=Tk()

to

        self.Eenu=Toplevel()
