It looks like you're running Cesium locally without a server. Since the browser can't access your filesystem, you'll get an error like that when loading images/textures.
See the setup instructions here for how to run a local development server:
Or alternatively, if you have Python installed, you can just run a local web server that way too. More on that here:
I hope his helped!
In particular, when loading imagery from a server, make sure CORS is enabled. See the Imagery Tutorial section on CORS for a thorough explanation.
