    Change Title Text of Cloud Links

    Use the topic_count_text_callback argument to pass in a new callback function. The original function default_topic_count_text() is located in /wp-includes/category-template.php This example changes the title text from the default “topics” to “pictures”.

    <?php 
    	wp_tag_cloud( array( 'topic_count_text_callback' => 'my_tag_text_callback' ) ); 
    
    	function my_tag_text_callback( $count ) {
    		return sprintf( _n( '%s picture', '%s pictures', $count ), number_format_i18n( $count ) );
    	}
    ?>
