Script#: 542356432

It inserts a slider beneath the image (only on thetheoristgateway website) which allows manipulation of image brightness.

ORIGINAL SCRIPT: https://github.com/LetsGoGT/GTARG/blob/master/ImageBrightness.md

This is all through vanilla js (no external libraries such as JQuery), and is done by replacing an image with an HTML5 canvas element - which can have filters applied to it.
