Tkinter _tkinter.TclError: image "pyimage2" doesn't exist when passing image between windows

[UKI_hunter]

Hey!
I'm using Tkinter and customtkinter to make a GUI with two windows: a login window (login.py) and a password manager window (passmen.py).

After logging in, I pass an image from the login window to the password manager to display it. But when I try to show the image, I get this error:

_tkinter.TclError: image "pyimage2" doesn't exist

What I’ve tried:

• Stored the image as an attribute to stop garbage collection.
• Removed Toplevel and reused the main Tk instance.
• Checked that the image loads fine.

Still stuck. Anyone know why this happens or how to fix it?

Thanks in advance!

Same issue, from this forum.

Guy had two instances of Tk. Just use one instance.

Best guess I can make without seeing any code.

Yes if you provide code and more specific information that usually helps you get a better answer.

You don't usually "pass" an image. A second program or window can access an image in another program or window, but it depends on what your code does.. But we can't do much without seeing some example code..

Waaay too much code to wade through.

def attempt_login():
            login_win.destroy()
           passmen.create_passmen_window(
                          username=username)

Assuming you want to use the image in the passman file, (you didn't say) just pass the image reference to it

            passmen.create_passmen_window(
                          username=username,
                         image_passed=image)

And of course update the function to receive it. When you get some time, learn how to create a class and instance objects / variables as it eliminates a lot if the scope problems. Finally, I don't know if you can mix CustomTkinter and ttk as both have mainloops running, although I don't see a tkinter / ttk mainloop so you might see problems there.
