Icon howto?

["Jonathan Roberts" <jonathan roberts uk googlemail com>]

Hi all,

I was wondering if somebody could advise me of a tutorial on how to
create icons (file formats, names etc), and how to install them
somewhere that I can test them?

Not much of an artist myself, but I was inspired by the recent idea of
simple black and white icons for small sizes so might have a crack at
something along those lines...
