How do I insert a JPEG image into a python Tkinter window?

Try this:

import tkinter as tkfrom PIL import ImageTk, Image#This creates the main window of an applicationwindow = tk.Tk()window.title("Join")window.geometry("300x300")window.configure(background='grey')path = "Aaron.jpg"#Creates a Tkinter-compatible photo image, which can be used everywhere Tkinter expects an image object.img = ImageTk.PhotoImage(Image.open(path))#The Label widget is a standard Tkinter widget used to display a text or image on the screen.panel = tk.Label(window, image = img)#The Pack geometry manager packs widgets in rows or columns.panel.pack(side = "bottom", fill = "both", expand = "yes")#Start the GUIwindow.mainloop()
