how about something like this...

#!/usr/bin/perl
use strict;
use warnings;

my $current;
my %data;
my $ok;

while (<DATA>) {

        next unless ( /^checking image file/ ... /^checking files file
+/ );  

        if ( /^checking image file <(.*?)>$/ ) {    # first line match
                $current = $1; $ok = 1;             # set our file and
+ status
                next;
        }

        if ( /media does not exist/ ) {             # a bad line 
                $ok = 0;
                next;
        }

        if ( /^checking files file/ ) {             # last line match
                $data{$current} = $ok ? "ok" : "bad";
        }
}

END {
        foreach my $k (sort keys %data) {
                print "$k is $data{$k}$/";
        }
}
