Which is all fine and dandy if you have the context of the <img> tag,
i.e. you're coding a browser.  But, what about other components like
caches?  How would they even know to use a binary sniffer, without
the foreknowledge provided by the <img> tag?  Much better for the
sender to explicitly indicate the payload's codec.
