  31 =head1 DESCRIPTION
  32
  33 This script is called and presents the user with an interface allowing him/her to upload a single cover image or bulk cover images via a zip file.
  34 Images will be resized into thumbnails of 140x200 pixels and larger images of
  35 800x600 pixels. If the images that are uploaded are larger, they will be
  36 resized, maintaining aspect ratio.
