tkinter doesn't open image via function

Question

Tkinter doesn't open the image. We can ask the opening incorrectly, we need help. I need it to open the image through the menu. be sure to use pil, as the image can be anything. There are no errors in the syntax. Thank you = )

from tkinter import Tk, Frame, Menu, Canvas, PhotoImage
import easygui
from PIL import Image, ImageFilter, ImageTk

def input_file():
    a = easygui.fileopenbox(filetypes=["*.jpg"])
    original = Image.open(a)
    original = original.resize((799, 799), Image.ANTIALIAS)
    photoimg = ImageTk.PhotoImage(original)
    canvas = Canvas(root, width=799, height=799)
    imagesprite = canvas.create_image(10, 10,anchor='nw', image=photoimg)
    canvas.pack()
    return (imagesprite)

root = Tk()
root.title("Sputnikeca")
#root.iconbitmap('путь к иконке')
root.geometry("800x800+0+0")

my_menu = Menu(root)
root.config(menu=my_menu)

# Create a menu item

file_menu = Menu(my_menu)
my_menu.add_cascade(label = "Файл", menu=file_menu)
file_menu.add_command(label = "Импорт...", command=input_file())
file_menu.add_separator()
file_menu.add_command(label = "Выход", command=root.quit)

root.mainloop()

Here is what you have to do to solve the issue:

def input_file():
    global photoimg #keeping a reference
    a = easygui.fileopenbox(filetypes=["*.jpg"])
    original = Image.open(a).resize((799, 799), Image.ANTIALIAS) #calling it all in one line
    photoimg = ImageTk.PhotoImage(original)
    canvas = Canvas(root, width=799, height=799)
    imagesprite = canvas.create_image(10, 10,anchor='nw', image=photoimg)
    canvas.pack()
    return imagesprite

and then later remove the () around your function:

file_menu.add_command(label = "Импорт...", command=input_file)

What is being done?

In the first set of code im keeping a reference to the image so the image is not garbage collected by python. You can do so either by saying imagesprite.image = photoimg or global photoimg on top of the function. I also resized the image in the same line that I opened the image, to reduce codes.
And in the second set of codes, im just removing () so that the function is not called(invoked) before choosing the menu item.

And also tkinter itself has a filedialogbox that works like your easygui.fileopenbox(filetypes=["*.jpg"]), read some docs here

from tkinter import filedialog

a = filedialog.askopenfilename(title='Choose a file',initialdir='C:/',filetypes=(('All Files','*.*'),("JPEG 
Files",'*.jpeg')))

Hope this helped you solve the error, do let me know if any doubts.

Cheers

File "canvas.py", line 11, in input_file imagesprite.image = photoimg #keeping a reference AttributeError: 'int' object has no attribute 'image' There is a new error after 3 points! Thanks for the help from a student from the Russian Federation

If I am not mistaken, your menu opens as soon as you run the application, not when you click the import button.

It's because you need to pass the callback to the add_command, but you're calling the method instead

file_menu.add_command(label = "Import...", command=input_file())

Remove the () from input_file(). just pass input_file. it will not call the method directly anymore.

file_menu.add_command(label = "Import...", command=input_file)

This wont solve the problem of image not appearing, i guess

@CoolCloud That's why I added If I am not mistaken, as the question is not much clear, and it looks like OP is not comfortable with English, ' I need it to open the image through the menu. ' is what I thought was the the problem.
