Help with Tkinter
I'm using an image as a Label, and it creates a background for the image. I looked for solution everywhere. The image is not transparent no matter what I do.

You can use the Tkinter canvas ...
Code:
''' Tk_Canvas_Image_b64_btn.py
a base64 encoded GIF image string is simple to use with Tkinter
use it for an image to put text on
'''

try:
    # Python2
    import Tkinter as tk
except ImportError:
    # Python3
    import tkinter as tk

# base64 encoded GIF image string
bt_yellow_oval_gif_b64='''\

Hi
b49P23TIvg: TNX, but that''s not the issue

Dietrich:
there's no background when I use the create_image to display an image.
I didn't really understand the code, but I'll probably use the canvas as a workaround (it's not ideal, but I can't find a solution).

TNX

Are you looking for an alpha channel in tkinter?

yes,
I've found a few websites that claimed that there ways to use alpha channel in tkinter but they didn't work.
