Optimizing for the user choosing to right-click=>Save seems like a
much more niche case than linking to a file that should be downloaded.

Plus, you could address it by just wrapping the <img> in an <a>:

<a href=uglyurl.jpg download=prettyurl.jpg><img src=uglyurl.jpg></a>

Alternately, there's nothing saying that @download can't be useful on
<img> directly.  It would still be embedded normally, but @download
would set the download filename the same way that it does on <a>.  (It
seems more obvious to me that the download filename is in @download
than @filename - the latter seems likely to confused people into
thinking that it's involved somehow in linking to the image, or that
you're required to set the filename on all images).
