  62 =head1 SYNOPSIS
  63
  64 picture-upload.pl
  65
  66 =head1 DESCRIPTION
  67
  68 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.
  69 Files greater than 100K will be refused. Images should be 140x200 pixels. If they are larger they will be auto-resized to comply.
