Homepage thumbnails missing

[addieotto]

I convinced a friend to try a revolution theme and now that he's having a problem he's asked me to help so I'm turning to you all because I don't know what I'm doing :?

There is no thumbnail photo showing up on the home page when a post is created. I added a photo to the test post but I do not know if something else has to be done on the "post" end of things or if the language needs to be adjusted on the homepage end. Currently and empty box appears where the thumbnail should be.

The homepage reads:

<?php $recent = new WP_Query("cat=3&showposts=3"); while($recent->have_posts()) : $recent->the_post();?>

<div style="padding-top:10px;border-top:1px dotted #C0C0C0; clear:both;"></div>

<div style="float:left; margin:0px 10px 5px 0px;">
[img]<?php echo get_post_meta($post->ID, [/img]" alt="<?php echo get_post_meta($post->ID, "Theme Name", true); ?> Thumbnail" />
</div>

<h2><?php the_title(); ?></h2>
<?php the_content_limit(125, "Read more"); ?>

<?php endwhile; ?>

Help is greatly appreciated! Website is www.nathanwinograd.com/newsite thank you!
