Ok. :-)

The filename extension is left out to let the server negotiate with the
client whether to return a GIF file or a PNG file. PNG is the preferred
format but not all clients can handle it so there has to be a fallback to
the GIF files. This will of course fail if the server running the validator
does not have content negotiation enabled.
