No, the server does send the Content-Type header, but it's served with
content negotiation.  So if you request a PNG version, the server
returns a PNG image (with "Content-Type: image/png"), and if you
request a GIF version, the server returns a GIF image (with
"Content-Type: image/gif").  Usually your browser sends an Accept
header to tell the server what format your browser supports, and if
your browser supports PNG, then a PNG version will be served,
otherwise a GIF version will be served.

So if, for example, you link an HTML 4.0 logo on validator.w3.org,
I'd recommend to link it as "http://validator.w3.org/images/vh40",
but if you specifically want a GIF version, just download
