1.1 fetch: Same Origin Policy problem

Just starting! And already hitting a minor roadblock. Both the code I wrote and the [code from Github](https://github.com/CodingTrain/Intro-to-Data-APIs-JS/blob/source/module1/01_fetch_image/index.html) lead to an error in my browser when it tries to fetch the image:

> Cross-Origin Request Blocked: The Same Origin Policy disallows reading the remote resource at file:///home/bbausch/js-working-with-data/1.1-fetch/rainbow.jpg

This is Firefox 68 on Xubuntu. I solved the problem by hosting the picture on a web server (the node.js/express.js web server from video 2.1 :)), but I wonder why I am the only one with this problem?

**EDIT**: Dan uses live-server, and on its [web site](https://www.npmjs.com/package/live-server), I read

> AJAX requests don't work with the file:// protocol due to security restrictions, i.e. you need a server if your site fetches content through JavaScript.

So I feel validated! But my question remains - is everybody using live-server or are there other methods to get around cross-origin problems?

Commencez par l’exemple de fetch 1.1 lié et l’erreur Firefox signalée avec file://, puis comparez-le aux approches avec live-server et Node.js/Express mentionnées dans l’issue. Le travail est considéré comme terminé lorsque la manière prise en charge d’exécuter l’exemple est documentée et que la restriction pertinente du navigateur ainsi que les alternatives sont expliquées.
