hzemall, in your theme on single.php there is the beginning of the loop:
<?php if (have_posts()) : while (have_posts()) : the_post(); ?>
<div class="post">
After this there is something like this:
<h2 id="post-<?php the_ID(); ?>"><a href="<?php echo get_permalink() ?>" rel="bookmark" title="Permanent Link: <?php the_title(); ?>"><?php the_title(); ?> <small> von <?php the_author_posts_link(); ?></small></a></h2>
In this I linked the author to the author profile by <?php the_author_posts_link(); ?>. If you don’t want it as a link, you can use <?php the_author(); ?> instead.
To get a photo look for plugins with avatars or gravatars (I don’t know, because I don’t have them.)
Greetings,
Rita
