tarajaneirvine on "custom fields display tag on hover"

I have added custom fields to all my posts and they contain links to thumbnails, What I want to be able to do is on hover display the tag for each post in a div at the top of the page.


<?php $imgThumb = get_post_meta($post->ID,'img_thumb', true); ?>
<?php if($imgThumb !=""){ ?>
<div id="rollover2" style="margin-top:14px;width:300px;height:30px;display:none;">
<?php the_tags(''); ?>
</div>
" title="<?php the_title(); ?>"><?php echo "<img class='thumb' src='$imgThumb'/>" ?>
<?php } else { echo ''; } ?>

Could really do with some help, no one seems to know how to do this.,,,
