=head1 NAME
picture-upload.pl - Script for handling uploading of both single and bulk patronimages and importing them into the database.
=head1 SYNOPSIS
picture-upload.pl
=head1 DESCRIPTION
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.
Files greater than 100K will be refused. Images should be 140x200 pixels. If they are larger they will be auto-resized to comply.
