Can someone help me with source code on my Macbook air

A 404 status code indicates that the HTTP protocol could not find the requested resource ... but may be available in the future. This is a browser client-side status code. That means that the issue is on the client and not the server side of HTTP communications. In your image, the error is being sent as the browser cannot find the specific jpg files.

An index of all its contents should appear.

If some of them won't load, a simple first step is to restart your router.

For what it's worth I was able to load every file I attempted to load.

Example: hunt-smallman.jpg
