This patch avoids using file-level private variables in subroutines
by passing the needed variables as parameters to the subroutines.
To test (under Plack):
1) Try uploading a patron image without applying the patch. Notice
it fails.
2) Apply patch.
3) Try uploading a patron image again, noticing this time it succeeds.
To test (under Apache):
1) Apply patch.
2) Try uploading a patron image, confirm that it works.
