Tkinter : Adding image to the window (create_window on the canvas is used)

Question

I want to add an image in right top of the window. This is the image I want to put up there : https://imgur.com/a/YjRWmMh

I tried this :

photo = PhotoImage(file="C:\Users\sel\Desktop\logo.png")

tk.label = Label(canvas, image=photo)

canvas.create_window(125,10, window=photo, anchor=tk.NW)

But it didn t work.I got this error.

File "", line 22

photo = PhotoImage(file="C:\\Users\\sel\\Desktop\\logo.png") ^

SyntaxError: (unicode error) 'unicodeescape' codec can't decode bytes in position 2-3: truncated \\UXXXXXXXX escape

Answer 1

I think it's because you supply the create_window function with the image instead of the label containing the image. Try using create_image instead:

photo = tk.PhotoImage(file=r"C:\Users\sel\Desktop\logo.png")
canvas.create_image(125,10, image=photo, anchor=tk.NW)

Answer 2

create_window is used to put tkinter's widget on canvas.

PhotoImage is not widget. But Label (with PhotoImage inside) is a widget.

So use window=label instead of window=photo

photo = tk.PhotoImage(file="C:\Users\sel\Desktop\logo.png")
label = tk.Label(canvas, image=photo)
canvas.create_window(125,10, window=label, anchor=tk.NW)

But you would rather use create_image as in @figbeam's answer.
