hmm there is a freeware version of PPaint, on aminet:
AMINET VERSION
This archive contains a complimentary edition of Personal Paint
version 7.1b, for exclusive distribution through the Aminet internet
archives. This is the full and latest commercial version (not a
demonstration version). The main differences between this distribution
and the commercial product are some tutorials and artwork add-ons, which
for space reasons would not be practical to include in this archive, and
the GIF I/O library, which cannot be redistributed due to licensing
restrictions.
