<?php $category = $record ['record']; { ?>
<?php foreach($db->query("select * from blog where category = '$category' order by id desc") as $row){ ?>
<li>
    <a href="<?php echo $row['image']; ?>">
        <div class="gallery-item"><img src="<?php echo $row['image']; ?>" alt="<?php echo $row['title']; ?>"></div>
    </a>
</li>
<?php } } ?>

If you want the most recent post, you could change your SQL to select it. Try something like this:

select * from blog where category = '$category' order by {DATE_FIELD} desc limit 1

You need to exchange the string {DATE_FIELD} with the actual date field in your table. This select would return the most recent dataset and only that one.

EDIT: You can also sort by youre id if the date isn't changed or the changed date is stored in another field.

select * from blog where category = '$category' order by id desc limit 1
