  61 picture-upload.pl - Script for handling uploading of both single and bulk patronimages and importing them into the database.

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