Is it possible to get duplicate images of the

Python Wikipedia API
like hashlib?
Comparing two images with different sizes to see if they display
(roughly) the same picture is not possible with standard hashing
functions, as standard hashing functions are specifically made to
change strongly when the input changes slightly. It is certainly not
possible to query the mediawiki database for images 'that look like'
other images.
However, services such as TinEye and Google Image Search exist.
Possibly they have an API you can use? Wikipedia also has some
information on this subject:
