No; it's a temporary implementation of the proposed solution; which will
presumably be replaced by a server-side implementation.

The process consumes large amounts of RAM, not disk space.  There would be
precious little point in a rescaling process which produced an output file two
hundred times the size of the input.

Allowing a process to exist which is known to consume measurable quantities of
a resource is a DoS vector: saving a page which requests the image above in
every size between 1 and 5000px would not exceed the maximum page size, but
could easily send an image scaler into swap trying to produce all the necessary
thumbnails.

That.
