i have tried for hours now, and i am very upset, cause this should be super simple. File::Fetch::WARN, as I have read, when set to 0 will stop things from being carp'd (which outputs to STDOUT, no?). but, my code emits an error message when $PARAMS{url} does not exist when i need it to just shutup and let me handle the error. so i do this in my code: 
use strict;
use warnings;
use CGI::Carp qw(fatalsToBrowser);
use File::Copy;
use File::Path qw(remove_tree rmtree);
use File::Fetch;
$File::Fetch::WARN = 0;
use Fcntl;
use URI::Escape;

use English;

my $ff = 0;
eval { $ff = File::Fetch->new(uri => $PARAMS{url}); };

if (not $ff) {
  if ($DEBUG_OP_ADD_COVER_PHOTO) {
    $output .= "failed to retrieve image: " . $ff->error . "<br>\n";
  } else {
    print error_redir(redirrer($OP_QUERY, $OP_FILE_MANAGER, $FOLDER_QU
+ERY, $FOLDER), "Failed to Retrieve Image: " . $ff->error);
    exit 1;
  }
}

the eval was added in as a suggestion to suppress the warning, but that doesn't work. $File::Fetch::WARN = 0 has no affect!

the fetching process emits a completely different error message, and it's printed (i presume to STDOUT) before i get to print anything to STDOUT! which causes "internal server error", and i can't get the thing to stop printing that damn junk out, it 'breaks' things!

Note: whilst $DEBUG_OP_ADD_COVER_PHOTO = 1, the error message emitted is: could not retrieve file: Command failed:. Nowhere in my code have I asked for that to be printed out.

Edit: Added "use" statements which may affect your answer. the code in this post is only a very small part of a much larger program.

I was pondering why the ball was getting bigger, and then...it hit me!
