Images are very useful objects in any application. We can process Images in a Tkinter application using the Pillow or PIL package in Python. There are several built-in functions such as loading an image, extracting an image, configuring the image pane, etc.
Example
In this example, we will add by asking the user to select an image from a dialog box and then, display it using the Label widget.
#Import the Tkinter library
from tkinter import *
from tkinter import ttk
from tkinter import filedialog
from PIL import Image, ImageTk
#Create an instance of Tkinter frame
win= Tk()
#Define the geometry
win.geometry("750x350")
win.title("Image Gallery")
def select_file():
path= filedialog.askopenfilename(title="Select an Image", filetype=(('image files','*.jpg'),('all files','*.*')))
img= Image.open(path)
img=ImageTk.PhotoImage(img)
label= Label(win, image= img)
label.image= img
label.pack()
#Create a label and a Button to Open the dialog
Label(win, text="Click the Button below to select an Image", font=('Caveat 15 bold')).pack(pady=20)
button= ttk.Button(win, text="Select to Open", command= select_file)
button.pack(ipadx=5, pady=15)
win.mainloop()Output
Running the above code will display a window that contains a button to select the image file from the directory and display the image on the window.
Now, select any image from the local directory and display the output on the screen.
