Since #15, the FROM command can use a (remote) URL as an image source. However, this does not include any caching, which is desirable for larger images. Consequently, caching should be implemented.
A possible problem is that the remote image for a URL has changed. At least for HTTP/S the Last-Modified field could be considered.
