I want smaller featured image on the post page.

Please follow these instructions:

1. open single.php
2. find these lines:

<?php $postThumbnail = tb_get_thumbnail($postID, 'dfl'); ?>
 <?php if ($postThumbnail) { ?>

 <?php $imageFull = wp_get_attachment_image_src( get_post_thumbnail_id($postID), 'full'); ?>

 <div class="doubleFramed large alignleft">
 <a href="<?php echo $imageFull[0]; ?>" title="<?php echo $postTitle; ?>">
 <?php echo $postThumbnail; ?>
 </a>
 </div>
 <?php } ?>

and change them to read:

<?php $postThumbnail = tb_get_thumbnail($postID, 'dfm'); ?>
 <?php if ($postThumbnail) { ?>

 <?php $imageFull = wp_get_attachment_image_src( get_post_thumbnail_id($postID), 'full'); ?>

 <div class="doubleFramed medium alignleft">
 <a href="<?php echo $imageFull[0]; ?>" title="<?php echo $postTitle; ?>">
 <?php echo $postThumbnail; ?>
 </a>
 </div>
 <?php } ?>
