python AttributeError: module 'PIL.Image' has no attribute 'save'

This error occurs when the 'save' method is called on the 'PIL.Image' module, which is not defined.

To fix this error, make sure you are calling the 'save' method on an instance of the 'Image' class imported from the 'PIL' module, like this:

from PIL import Image

img = Image.open('image.jpg')
img.save('new_image.jpg')

This should save the image in the specified format with the specified name.
