How to insert an image with a transparent background on top of another in PIL?

Question

Python

I need to insert an image with a transparent background on another
I used:
img.paste(img2,box,mask = img2)
But if the image is white then an error is thrown:

Traceback (most recent call last):
  File "C:/Users/Даниил/PycharmProjects/discordbot/test.py", line 32, in <module>
    img.paste(item, (3, 3), mask=item)
  File "C:\Users\Даниил\AppData\Local\Programs\Python\Python36\lib\site-packages\PIL\Image.py", line 1421, in paste
    self.im.paste(im, box, mask.im)
ValueError: bad transparency mask

What do you advise?

Answer 1

You need nodejs , and then the commands are written there.
npm install peer - install peer package
peerjs --port 9000 --key peerjs - and this command, as I understand it, starts the server and port 9000

Answer 2
