Im trying to add a div for just one category

Question

So as the title says im trying to add a div class to the thumbnails from a single category. Im trying to use this code:

 if (in_category( 'Expired' )) : ?><div class="expire">

This is the single post code im trying to add it to:

 <?php
        if(has_post_thumbnail())  {
            the_post_thumbnail(
                array($theme->get_option('featured_image_width_single'), $theme->get_option('featured_image_height_single')),
                array("class" => $theme->get_option('featured_image_position_single') . " featured_image")
            );
        }
    ?>

And this is the div class ive created in the stylesheet:

.expire {
position: absolute;
bottom: 10px;
background:url(images/sample-expired.png) no-repeat ;
width: 100px;
height:60px;
text-align: center;
padding: 4px;
border-radius: 10px;
left: 2px;
}

Any ideas where in the code I should paste this? or any help as to getting this implemented? Thanks heaps

To wrap the thumbnail wit I would do something like this:

First. Create the expire class string

$expire_class = in_category('expired') ? 'expire' : '';

Then, wrap your post thumbnail code with this:

<div class='<?php echo $expire_class; ?>' > 
[put your thumbnail code here]
</div>

So, it looks like this:

<?php
$expire_class = in_category('expired') ? 'expire' : '';
if(has_post_thumbnail())  {
        ?><a href="<?php the_permalink(); ?>"><div class='<?php echo $expire_class; ?>' > <?php the_post_thumbnail(
            array($theme->get_option('featured_image_width'), $theme->get_option('featured_image_height')),
            array("class" => $theme->get_option('featured_image_position') . " featured_image")
        ); ?></div></a><?php  
    }
?>
