:loading :loaded :missing :corrupt

Maybe this exists or was discussed but I missed it. Excuse me if so. 
Pseudo-class selectors I wish were available are for images relate to 
their status in loading, so maybe a remote image could be hidden when 
the network becomes isolated, etc. 

Distinct states that would be useful to recognize include:

:loading,
:loaded,
:missing,
:corrupt

These could be applied to other media as well.
