Radom post image/link based on custom taxonomy

Question

How would I make a widget to display a random post's image and permalink? I would like it to pull from a specific custom content type and only posts have set the custom field of "featured" to "yes".

Answer 1

<?php query_posts( 'cat=36&post_type=athletes&showposts=1&orderby=rand'); ?>

changed to :

      <?php
$args = array( 'numberposts' => 36,'category'  => '1','post_type'  => 'athletes', 'orderby' => 'rand');


$lastposts = get_posts( $args );
foreach($lastposts as $post) : setup_postdata($post); ?>
    <h2><a href="<?php the_permalink(); ?>"><?php the_title(); ?></a></h2>
<?php endforeach; ?>
