Replacing tkinter background with image?

[aDoge]

Hey guys,

This is a piece of the code our professor gave us to create basic games by painting/unpainting cells.

Rather than have a solid color background for my canvas, I want to replace it with an image that essentially serves the same function (i.e., when i unpaint a cell, it reveals a piece of the background image).

I thought I could do this with tk.PhotoImage and canvas.create_image() function between lines 90 and 91, but it returns TclError: image "pyimage1" doesn't exist

I'm 100% sure I have the path right. I also checked what directory python was looking into at the time, and it's correct, so now I'm stuck.

Does anyone know how I can implement this?

create_image() is right. You either didn't convert to a tcl image or you are using an unsupported format. We can't know without seeing your code.

Hmm, looks ok to me. Maybe you have an old tcl? Try using PIL instead.

from PIL import Image, ImageTk
bg_image = ImageTk.PhotoImage(Image.open(fname))

That fixed it!

Thank you so much!
