extracting hypercard picts

[cowhead]

This was covered recently, but I've forgotten what the upshot was.
Appologies.  How does one efficiently extract pictures stored in the
resource fork of a hypercard project?  How about pictures saved within a
Supercard project (directly on a card)
I tried with graphic convertor, but couldn't get it to recognize either
file type.  Also, Resedit doesn't seem to offer any easy batch export of
pict images.
Thanks in advance!
