For anyone who is wondering,
Plucker is a PalmOS offline html/text reader, written in python and under the GPL. It uses zlib compression to convert html to the Palm pdb format. It's the most useful application for the Palm. I've got an old Palm IIIxe, and I'm carrying around the RUTE Textbook, several Python tutorials, Perl tutorials, Paradise Lost (from Project Gutenburg), Cory Doctorow's short stories, etc. It's simply fantastic.
However, sorry chii-chan, I can't answer your question. I always exclude images because they're too much for my poor old Palm IIIxe.
You might want to check the version of python installed on your machine. I found that the newest plucker requires at least 2.3.3.
