<?php
$posttags = get_the_tags(); // Get articles tags
$home = get_bloginfo('url'); // Get homepage URL

// Check tagslug.png exists and display it
if ($posttags) {
 foreach($posttags as $tag) {
       $image = "http://cdn.css-tricks.com/images/tag-images/$tag->slug.png";

       if (file_exists("images/tag-images/$tag->slug.png")) {
         echo '<a href="' . $home . '/tag/' . $tag->slug . '" /><img title="' . $tag->name . '" alt="' . $tag->name . '" src="' . $image . '" /></a>';

       // If no image found, output something else, possibly nothing.
       } else {
         echo '<p>Not found</p>';
       }
  }
}
?>

This code belongs inside the loop. It will look in a specific directory for any images that match the slugs of article tags, display them and link them to the relevant tag archive.

The image that shows for the author comes from the email address set for that user which goes to a corresponding Gravatar. The display name and bio come from the User settings area in the Admin.

<div class="author-box">
   <div class="author-pic"><?php echo get_avatar( get_the_author_email(), '80' ); ?></div>
   <div class="author-name"><?php the_author_meta( "display_name" ); ?></div>
   <div class="author-bio"><?php the_author_meta( "user_description" ); ?></div>
</div>

That should be all the CSS hooks you need to style up the area however you want. Note: some of these functions are WordPress 2.8 and newer only.

<?php wp_tag_cloud( array(

    'smallest' => 8,          // font size for the least used tag
    'largest'  => 22,         // font size for the most used tag
    'unit'     => 'px',       // font sizing choice (pt, em, px, etc)
    'number'   => 45,         // maximum number of tags to show
    'format'   => 'flat',     // flat, list, or array. flat = spaces between; list = in li tags; array = does not echo results, returns array
    'orderby'  => 'name',     // name = alphabetical by name; count = by popularity
    'order'    => 'ASC',      // starting from A, or starting from highest count
    'exclude'  => 12,         // ID's of tags to exclude, displays all except these
    'include'  => 13,         // ID's of tags to include, displays none except these
    'link'     => 'view',     // view = links to tag view; edit = link to edit tag
    'taxonomy' => 'post_tag', // post_tag, link_category, category - create tag clouds of any of these things
    'echo'     => true        // set to false to return an array, not echo it

) ); ?>

The default sizing, if none supplied, for this function is "pt" which is a bit unusual and often unreliable so make sure you change that parameter to how you size fonts normally on your site.

Less Weird Font Sizing

Tag clouds accomplish their varied font sizes by applying inline styling to each tag. The resulting font sizes can be really weird like style='font-size:29.3947354754px;'. Mike Summers proposes this solution:

<div id="tagCloud">
	<ul>
		<?php
			$arr = wp_tag_cloud(array(
				'smallest'             => 8,                      // font size for the least used tag
				'largest'                => 40,                    // font size for the most used tag
				'unit'                      => 'px',                 // font sizing choice (pt, em, px, etc)
				'number'              => 200,                 // maximum number of tags to show
				'format'                => 'array',            // flat, list, or array. flat = spaces between; list = in li tags; array = does not echo results, returns array
				'separator'          => '',                      //
				'orderby'              => 'name',           // name = alphabetical by name; count = by popularity
				'order'                   => 'RAND',          // starting from A, or starting from highest count
				'exclude'              => '',                      // ID's of tags to exclude, displays all except these
				'include'               => '',                      // ID's of tags to include, displays none except these
				'link'                       => 'view',             // view = links to tag view; edit = link to edit tag
				'taxonomy'         => 'post_tag',    // post_tag, link_category, category - create tag clouds of any of these things
				'echo'                    => true                 // set to false to return an array, not echo it
			));
			foreach ($arr as $value) {
				$ptr1 = strpos($value,'font-size:');
				$ptr2 = strpos($value,'px');
				$px = round(substr($value,$ptr1+10,$ptr2-$ptr1-10));
				$value = substr($value, 0, $ptr1+10) . $px . substr($value, $ptr2);
				$ptr1 = strpos($value, "class=");
				$value = substr($value, 0, $ptr1+7) . 'color-' . $px . ' ' . substr($value, $ptr1+7);
				echo '<li>' . $value . '</li> ';
			}
		?>
	</ul>
</div>

The result turns this:

<a href='url' class='tag-link-66' title='6 topics' style='font-size:29.3947354754px;'>Tag Name</a>

into this:

<a href='url' class='color-29 tag-link-66' title='6 topics' style='font-size:29px;'>Tag Name</a>

Notice the added bonus that the links has a class name of "color-29" now that it didn't before. Now you have a hook to colorize tag names based on their size.

function my_formatter($content) {
       $new_content = '';
       $pattern_full = '{(\[raw\].*?\[/raw\])}is';
       $pattern_contents = '{\[raw\](.*?)\[/raw\]}is';
       $pieces = preg_split($pattern_full, $content, -1, PREG_SPLIT_DELIM_CAPTURE);

       foreach ($pieces as $piece) {

                       $new_content .= $matches[1];
               } else {
                       $new_content .= wptexturize(wpautop($piece));
               }
       }

       return $new_content;
}

remove_filter('the_content', 'wpautop');
remove_filter('the_content', 'wptexturize');

add_filter('the_content', 'my_formatter', 99);

This goes in the PHP in your functions.php file. Once done, you can use the [raw] shortcode in your posts: [raw]Unformatted code[/raw]

Add to functions.php file

remove_filter('the_content', 'wptexturize');
remove_filter('the_excerpt', 'wptexturize');
remove_filter('comment_text', 'wptexturize');
remove_filter('the_title', 'wptexturize');

the wptexturize function is responsible for lots of automatic alterations to text stored in WordPress like automatic elipses (...), em and en dashes, typographers quotes, etc.

Just post a link to a GitHub Gist and it will be nicely embedded. Or use the format this snippet provides and create the shortcode yourself. For your functions.php file:

<?php
// [gist id="ID" file="FILE"]
function gist_shortcode($atts) {
  return sprintf(
    '<script src="https://gist.github.com/%s.js%s"></script>', 
    $atts['id'], 
    $atts['file'] ? '?file=' . $atts['file'] : ''
  );
} add_shortcode('gist','gist_shortcode');

// Remove this function if you don't want autoreplace gist links to shortcodes
function gist_shortcode_filter($content) {
  return preg_replace('/https:\/\/gist.github.com\/([\d]+)[\.js\?]*[\#]*file[=|_]+([\w\.]+)(?![^<]*<\/a>)/i', '[gist id="${1}" file="${2}"]', $content );
} add_filter( 'the_content', 'gist_shortcode_filter', 9);
?>

Any of these formats will work:

You know, the one typically at yoursite.com/wp-login.php. These are things you would put in the active theme's functions.php file.

Change the Logo

Is the WordPress logo by default, this changes the file path of that image. Change file path and file name to your own needs.

function custom_login_logo() {
	echo '<style type="text/css">h1 a { background: url('.get_bloginfo('template_directory').'http://cdn.css-tricks.com/images/logo-login.gif) 50% 50% no-repeat !important; }</style>';
}
add_action('login_head', 'custom_login_logo');

Change the URL

... of where clicking that logo goes. By default it goes to WordPress.org, this will change it to your own homepage.

function change_wp_login_url() {
	return bloginfo('url');
}
add_filter('login_headerurl', 'change_wp_login_url');

Change the Title

That is, change the title attribute of the image you just replaced. This changes it to the name of your blog in the settings.

function change_wp_login_title() {
	return get_option('blogname');
}
add_filter('login_headertitle', 'change_wp_login_title');
