The browser DOES see it. The webserver will add the status by itself, or takes it from the Status header.
This means there'll be _two_ requests, one'll hit the request, one'll hit the image. If everything's fast enough, the user will never notice.

The 302 status is "Found", which tells the browser to re-request using the URL in the Location-header.
The 304 is "Not modified", telling my browser to use the cached version.
