Python insert image into Tkinter error

Question

I want to insert an image into my tkinter but I received error:

TclError: image "pyimage7" doesn't exist.

I am using WinPython-64-3.3.5.9. I tried "rozmery.gif" but didn't help.

    from tkinter import *        
    from PIL import ImageTk, Image

    app_root = Tk()

    #Setting it up
    img = ImageTk.PhotoImage(Image.open("rozmery.png"))

    #Displaying it
    imglabel = Label(app_root, image=img).grid(row=1, column=1) 

    app_root.mainloop()

I had the same error message. I restarted the kernel (Spyder) and it worked perfectly fine. I have this kind of issue sometimes where the code works just fine but it refuses to work. Restarting the kernel is often the only way.
