Indeed. An interesting use-case has come up on this list — use  
highest-resolution image when user chooses "Save As".

While it's not an earth-shattering feature, it's a nice touch a browser  
could do having information about image. It wouldn't be possible/sensible  
to do with a media query.

Even if there was support for something like <source  
media="user-action:save-as">, I can bet that less than 0.5% of pages would  
use it and do it correctly.
