#
# A ghetto way to download the photos (skipping sized and thumbnails)
# in a phpAlbum photo gallery.  Create a file called credentials.rb
# that looks like this:
#
#  HOSTNAME = 'example.com'
#  USERNAME = 'example_user'
#  PASSWORD = 'example-password'
#  FOLDER   = '/public_html/folder'
#
# Photos will be downloaded to 'photos' unless you provide another
# output folder.
#
