That sounds good.

Actually, I wonder if it can't be made to work for non-imagemagick
images: by operating on image-specs, it should be possible to make the
code do things like "extract the filename, pass the file to `convert'
and create a new image-spec for that temp file", while on imagemagick
images it would just fiddle with the paramters like :height.
