For reducing high bandwidth usage network admins can limit file size to be uploaded on server by other users. Following script limits file size a user can upload:

function custom_gravatars( $avatar_defaults ) {
$myavatar = get_template_directory_uri() . ‘/images/custom-avatar.png’;
$avatar_defaults[$myavatar] = ‘people’;
return $avatar_defaults;
}
add_filter( ‘avatar_defaults’, ‘custom_gravatars’ );
}
You can embed SoundCloud in your WordPress posts using WordPress feature oEmbed. It supports auto embedding until your URL breaks the line. WP oEmbed library supports Twitter, YouTube and many other popular services. SoundCloud is not yet supported by WordPress but still you have it by using oEmbed with the help of this function: wp_oembed_add_provider()
Adding oEmbed for SoundCloud in WordPress:
Open your theme’s function.php file and add the following code:
function add_oembed_soundcloud(){
wp_oembed_add_provider( ‘http://soundcloud.com/*’, ‘http://soundcloud.com/oembed’ );
}
add_action(‘init’,’add_oembed_soundcloud’);
All done. Now you can simply paste SoundCloud URL on separate line and let oEmbed do auto-embedding.

$tags = wp_get_post_tags($post->ID);
if ($tags) {
echo ‘Related Posts’;
$first_tag = $tags[0]->term_id;
$args=array(
‘tag__in’ => array($first_tag),
‘post__not_in’ => array($post->ID),
‘showposts’=>5,
‘caller_get_posts’=>1
);
$my_query = new WP_Query($args);
if( $my_query->have_posts() ) {
while ($my_query->have_posts()) : $my_query->the_post(); ?>
<p><a href=”<?php the_permalink() ?>” rel=”bookmark” title=”Permanent Link to <?php the_title_attribute(); ?>”><?php the_title(); ?></a></p>
<?php
endwhile;
}
}
?>

You can highlight most popular content of your WordPress site in your sidebar. Copy-Paste the following code in your theme’s sidebar.php file:
<h2>Popular Posts</h2>
<ul>
<?php $result = $wpdb->get_results(“SELECT comment_count,ID,post_title
FROM $wpdb->posts ORDER BY comment_count DESC LIMIT 0 , 5″);
foreach ($result as $post) {
setup_postdata($post);
$postid = $post->ID;
$title = $post->post_title;
$commentcount = $post->comment_count;
if ($commentcount != 0) { ?>
<li><a href=”<?php echo get_permalink($postid); ?>” title=”<?php echo
$title ?>”>
<?php echo $title ?></a> {<?php echo $commentcount ?>}</li>
<?php } } ?>
</ul>
It displays most popular posts on your site’s sidebar.
For changing the number of posts to display in your sidebar:
Look-up for this line in the above code block: FROM $wpdb->posts ORDER BY comment_count DESC LIMIT 0 , 5″); and Replace 5 with the number of posts you like to display.
