IsADirectoryError: [Errno 21] Is a directory: 'data/marvel/thor'

Answer 1

If data/marvel/thor is a directory, please try follows.

import os
data_paths = [os.path.join(pth, f) for pth, dirs, files in os.walk('data/marverl/thor') for f in files]
data = [download_images(f, mmap_mode='r') for f in data_paths]

You need to provide a variable/place to store each image separately.
