I am trying to write a jpg to a sqlite database and read it back. The read-back info says that the file maybe corrupted. The original size is 120,453 and the read-back file is 120,895 consistently. 
use strict;
use warnings;
use util_routines;
use DBI;

my $my_picture_file = "c:\\users\\xxx\\work\\blob.jpg";
my $dbname = "a.dat";

my $dbh = util_routines::connect_to_sqlite($dbname);

create_my_blob();

open (my $MYFILE,'<', $my_picture_file)  or die "Cannot open file....$
+!";
my $data;
{
    local $/;
    $data = <$MYFILE>;
    close $MYFILE;
}
$data =~ s/^\s+//g;
$data =~ s/\s+$//g;

# insert image into table
my $sql = "INSERT INTO my_blob VALUES (?)";
my $sth = $dbh->prepare($sql) or die; 
$sth->execute($data) or die;

# retrieve image from table
$sql = "SELECT image FROM my_blob";
$sth = $dbh->prepare($sql) or die;
$sth->execute() or die;

my $ref = $sth->fetchrow_hashref;
my $newdata = $$ref{'image'};

$newdata =~ s/^\s+//g;
$newdata =~ s/\s+$//g;

open (my $OUTPUT, '>', "output_blob.jpg") or die "$!\n";    
print $OUTPUT $newdata;
close $OUTPUT;

$sth->finish;
$dbh->disconnect;

sub create_my_blob {
    $dbh->do('drop table my_blob');
    my $sql = qq/create table my_blob (image blob)/;
    $dbh->do($sql) or die "\n\n$DBI::errstr";
    print "Created my_blob\n";
    return;
}
__END__
