  70
  71 =head1 DESCRIPTION
  72
  73 This script is called and presents the user with an interface allowing him/her to upload a single patron image or bulk patron images via a zip file.
  74 Files greater than 100K will be refused. Images should be 140x200 pixels. If they are larger they will be auto-resized to comply.
