Tutorial: Pull Images from the Web in Unity WebGL

Downloading images from the web is a natural thing you might want to do in a WebGL game. But it’s not as straightforward as it should be! You get the dreaded CORS error (in WebGL only!)

This tutorial shows you how to use a service called Filestack that gets you around CORS errors to download images from the internet in Unity WebGL Builds.
