@t31os probably doesn't want their user name in the title and edited it. There's no need to put usernames in titles of threads.... it won't get any special attention. You're best to just ask your question and see who answers. Many people have much to offer here.
In regards to your question....you want a thumbnail beside your title on each post. Times have changed, WP has changed. Its easier to do now.
First, learn how to use thumbnails in general.
http://markjaquith.wordpress.com/2009/12/23/new-in-wordpress-2-9-post-thumbnail-images/
is a great writeup on how to use thumbnails.
I implement it on my site here, and I think I do exactly what you are asking.
read the tutorial and set up your theme.
my functions.php looks like:
// THIS IS THUMBNAIL SUPPORT
if ( function_exists( 'add_theme_support' ) ) { // Added in 2.9
add_theme_support( 'post-thumbnails' );
set_post_thumbnail_size( 50, 50, true ); // Normal post thumbnails
add_image_size( 'single-post-thumbnail', 300, 999 ); // Permalink thumbnail size
add_image_size( 'title-image', 50, 27 ); // Title mini photo
}
this all sets up the thumbnails, and gets various sizes. The tutorial will help you understand that.
This portion here:
add_image_size( 'title-image', 50, 27 ); // Title mini photo
}
specifically sets up a little icon sized image for beside my titles
then in my index.php, before the line that calls my title, which looks like:
<div class="titleText"><a href="<?php the_permalink() ?>" rel="bookmark" title="Permanent Link to <?php the_title(); ?>"><?php the_title(); ?></a></div>
I've inserted:
<?php the_post_thumbnail('title-image', array('class' => 'titleImage', 'alt' => 'Title Icon')); ?>
which drops in the icon sized image (title-image) I set up previously in functions.php. It also gives it a class of titleImage for my css
and in my css I have
.titleImage {
margin: 9px 10px 0 5px;
float: left;
}
which gives it a margin of space, and floats it to the left of my title
This probably can't be directly copied into your theme without modification, but this is how it's done. With my stuff here and that tutorial, you should be able to get something going
