I did that, I wanted an image to show for every post that I put up. Since I'm the only one posting in that blog, it would only be for me.
<?php if ($posts) : foreach ($posts as $post) : start_wp(); ?>
<?php the_date('','<h2>','</h2>'); ?>
<h3 class="storytitle" id="post-<?php the_ID(); ?>"><a href="<?php the_permalink() ?>" rel="bookmark" title="Permanent Link: <?php the_title(); ?>"><?php the_title(); ?></a></h3>
<div class="meta"><?php _e("Filed under:"); ?> <?php the_category() ?> — <?php the_author() ?> @ <?php the_time() ?> <?php edit_post_link(); ?></div>
<?php the_content(); ?>
<img src="http://davensjournal.com/images/davenbl21.gif" />
As you see, the image comes after the post about the blog. At that point, it's whatever you want to be there.
