=head1 NAME

mkthumbs - Makes thumbnails in .thumbnails dir. Suitable for gqview etc.

=head1 DESCRIPTION

I use gqview, it makes thumbnails, but very slowly.
The program 'epeg' makes them incredibly quick at low quality.
This uses epeg to create thumbnails that will be accepted by gqview so you won't have to wait.
