How is that trivial? I might be able to do that on my simple PHP-based 
website, but I don’t have the code for it, and I am not exactly looking 
forward to facilitating that. On non-dynamic web sites it’s even less of 
an option. More so, would anyone be actually going to take the effort to 
do that? Doubt it.

The caching mechanism would also heavily impact my space allowance, and 
having the original as an uncompressed image even more so.

With regard to the ‘fallback’ technique in XHTML 2.0 where one can nest 
a number of image sources which are resolved based on the browser’s 
support for the type - I am not particularly fond of that application 
(just one of the many though), but I think it is nice to offer such an 
alternative to content negotiation over HTTP. Moreover, it mainly comes 
with the current methods in XHTML 2.0 ‘for free’, and is not a goal by 
itself for structuring things the way they are.
