Retrieve post thumbnails

<?php
/*
Template Name: Ron's WordPress Answers Template

include_once('header.php');
$args = array(
    'posts_per_page'  => 5,
    'offset'          => 0,
    'category'        => '',//you have to use the category id # here not the name of the cat
    'orderby'         => 'post_date',
    'order'           => 'DESC',
    'post_type'       => 'post',
    'post_status'     => 'publish',
    'suppress_filters' => true );
$posts = get_posts( $args );
global $post;
foreach( $posts as $post ){ 
setup_postdata($post); 
?>
<div class="post">
<p><a href="https://wordpress.stackexchange.com/questions/107227/<?php the_permalink() ?>" rel="bookmark" title="Permanent Link to <?php the_title(); ?>"><?php the_title(); ?></a></p>
<div class="meta">
By <?php the_author() ?>
</div>
<div class="storycontent">
<?php 
if ( has_post_thumbnail() ) { 
  the_post_thumbnail();
}else{

} 
?>
<?php the_content(); ?>
</div>
</div>
<?php 
       }
include_once('footer.php');  ?>

the_post_thumbnail(‘thumbnail’); // Thumbnail (default 150px x
150px max) the_post_thumbnail(‘medium’); // Medium resolution
(default 300px x 300px max) the_post_thumbnail(‘large’); //
Large resolution (default 640px x 640px max)
the_post_thumbnail(‘full’); // Full resolution (original
size uploaded)

I like to use ccs like this to make sure the images display “nicely”.

.storycontent img{
max-width: 100%;
height: auto;
}
