Huh?  C-x C-w is a command to write the current buffer to a specified
file.  It doesn't edit anything.

That's unreasonable: visiting an image file automatically shows it as
an image, so from a user perspective, I simply visited a file and want
to save it to another file.  A practical use-case would be to display
an image file from a compressed archive, then write it to a file, thus
effectively extracting it from the archive.  I know about C-c C-c, but
it's a nuisance, and shouldn't be required, IMO.
