You might want to check out the comments_array filter. In 3.5, it is applied in Line 891 of wp-includes/comment-template.php: $wp_query->comments = apply_filters( ‘comments_array’, $comments, $post->ID );
Here is a way: // listen for post being published add_action(‘publish_post’, ‘dreis_random_featured_image’); function dreis_random_featured_image() { global $post; // find one random image $args = array( ‘post_type’ => ‘attachment’, ‘post_mime_type’ => ‘image’, ‘post_status’ => ‘inherit’, ‘posts_per_page’ => 1, ‘orderby’ => ‘rand’ ); $random_image = new WP_Query($args); foreach($random_image as $image){ // set as thumbnail set_post_thumbnail($post->ID, $image->ID); } … Read more

The author is using string functions for single-byte encodings: $url = substr($line, $lastDelimiterPos + 1 ); $keywords = substr($line, 0, $lastDelimiterPos); But in WordPress everything is encoded in UTF-8, a multi-byte encoding.
