I mean that I take this out from the mainloop2 sub:

   if (-e "imageHandling.pl") {

        my $app = do "imageHandling.pl";
        if (!defined($app)) {
            die "imageHandling not loaded.\n";
        }
    }
    else {
        print "imageHandling.pl not found.\n";
        exit;
    }

and put it "globally".
