# USAGE: ./make_lazy $AUTHORS_NAME $FIELD_TO_REMOVE
# FIELD_TO_REMOVE is useful when the original author has
# added an aokp prefix to the image. We already know this
# will be an aokp related image, and is unneeded.
# Currently supported formats are .png and .jpg.
#
# In addition to most normal linux apps, this script will
# require the ImageMagick suit for thumbnail creation.
# You can find it here http://www.imagemagick.org/script/index.php

# first, make sure there is an author being added. If not, things
# break
