This plugin adds simple HTML tag generation API to WordPress, like these examples: 
 generates and prints <code><img src="/wp-content/<your-theme>/images/wordpress.png" alt="Wordpress" /></code>. 
 ‘my-image’)) ?> generates and returns almost the same tag, just with absolute url, id and alt attributes set manually. 
 term_id) ?> generates select tag with options taken from WP ‘category’ taxonomy and sets $term as selected item 
 rails-like “cycle” that returns “odd” on first call, “even” on second, “odd” on 
 third call, so on. reset_cycle resets the cycle. 
 shortcut for echo(get_post_meta($id, ‘meta_name’, true))
Form field generators for <code>text</code>, <code>checkbox</code>, <code>hidden</code> input types, <code>textarea</code>, and more tags. More docs coming soon, you can read the code to figure out other features for now.
