As far as I can tell, this would be pretty much what we are looking for, at
least for most of the usage.

If an image is used more than once into a document and is also used at
various sizes, I guess the result would be as many cropped images as needed
to cover all the needs in that particular document.

What do the devs say? Is this usable, implementable, doable?
