Below are 2 versions of what should be added to the bottom of your LocalSettings file. Believe the first one will work from v1.21 onwards as much as the second one, as well as the code it is attached to. This repository should be tagged if not.
/*
Modified to work with 1.25.
Antony D'Andrea - contactme at antonydandrea dot com
This also has a couple of bug fixes on the code, but the config below
along with the bug fixes definitely works in MediaWiki 1.25.

Modified to work with 1.21 and CloudFront.
Owen Borseth - owen at borseth dot us
LocalS3Repo modified to work with MediaWiki 1.21, maybe others, and CloudFront CDN. A maintenance script that I used to move my current
files over to S3 has been included; it will probably need to be slightly modified to work for you.
