patronimage.pl - Script for retrieving and formatting Koha patron images for display

=head1 SYNOPSIS

<img src="patronimage.pl?crdnum= />

=head1 DESCRIPTION

This script, when called from within HTML and passed a valid patron cardnumber, will retrieve the image data associated with that cardnumber if one exists, format it in proper HTML format and pass it back to be displayed.

if ($data->param('crdnum')) {
    $cardnumber = $data->param('crdnum');

}

# NOTE: Never dump the contents of $imagedata->{'patronimage'} via a warn to a log or nasty
# things will result... you have been warned!
