Ok, rather than uncompressed, use PNG. But content negotiation should
be something done by a server, not a user. A person's time is far more
valuable than the machine's. And I would be willing to bet the caching
mechanism wouldn't harm your space reserves that badly based on
graphic repetition we see in today's websites.

And I reject wholehardedly any argument that says the many should have
to do extra work because the few don't want to.
