15label1 = Label(app, image=image1, textvariable=labelText,
16               font=("Times New Roman", 24),
17               justify=CENTER, height=4, fg="blue")
18label1.pack()

1You need to apply the grid method to the label that contains the image, not the image object:
2
3bg_image = PhotoImage(file ="pic.gif")
4x = Label (image = bg_image)
5x.grid(row = 0, column = 0)
