   How do I wrap the post thumbnail with a permalink?
   Im using this function:

   
   // Add post thumbnail support in WP2.9
   if ( function_exists( 'add_theme_support' ) )
   add_theme_support( 'post-thumbnails' );
   
   // Add post thumbnail to post excerpt
   function my_post_title($title) {
   	if (is_home() || is_archive() || is_search()) {
   		return get_the_post_thumbnail(NULL, 'thumbnail', array('class' => 'alignleft')) . $title;
   	}
   	else {
   		return $title;
   	}
   }
   add_filter('thematic_postheader_posttitle', 'my_post_title');
   

   Thank you!

   hi cannobblo,

   This worked for me, maybe you can adapt it to what you need?

   // ads to each thumbnail a link to the permalink
   add_filter( 'post_thumbnail_html', 'my_post_image_html', 10, 3 );
   function my_post_image_html( $html, $post_id, $post_image_id ) {
   	$html = '<a href="' . get_permalink( $post_id ) . '" title="' . esc_attr( get_post_field( 'post_title', $post_id ) ) . '" rel="nofollow">' . $html . '</a>';
   	return $html;
   }
   function thumbnail_caption($html, $post_id, $post_thumbnail_id, $size, $attr)
   {
     $attachment =& get_post($post_thumbnail_id);
   
     // post_title => image title
     // post_excerpt => image caption
     // post_content => image description
   
     if ($attachment->post_excerpt || $attachment->post_content) {
       $html .= '<p class="thumbcaption">';
       if ($attachment->post_excerpt) {
         $html .= '<span class="captitle">'.$attachment->post_excerpt.'</span> ';
       }
       $html .= $attachment->post_content.'</p>';
     }
   
   	return $html;
   };
   add_action('post_thumbnail_html', 'thumbnail_caption', null, 5);

   this is even easier now w/ the featured image that started in WP 2.9

   add_theme_support( 'post-thumbnails' );
   
   //wrap thumbs in link to post
   function my_post_image_html( $html, $post_id, $post_image_id ) {
   	$html = '<div class="thumbnail"><a href="' . get_permalink( $post_id ) . '" title="' . esc_attr( get_post_field( 'post_title', $post_id ) ) . '">' . $html . '</a></div>';
   	return $html;
   }
   
   add_filter( 'post_thumbnail_html', 'my_post_image_html', 10, 3 );

   that wraps the thumbnails w/ the permalink... and to use it you just need to put the_post_thumbnail( 'thumbnail' ) into the excerpt

   // excerpt read more links and wrap excerpt in p tag
   function all_excerpts_get_more_link($post_excerpt) {
   	if ( has_post_thumbnail() ) {
   		$child_excerpt =  the_post_thumbnail( 'thumbnail' ) . '<p>' . $post_excerpt . '</p>' . '<p class="readmore"><a href="'. get_permalink($post->ID) . '">' . 'Continue Reading &raquo' . '</a></p>';
   	}
   	else {
   		$child_excerpt = '<p>' . $post_excerpt . '</p>' . '<p class="readmore"><a href="'. get_permalink($post->ID) . '">' . 'Continue Reading &raquo' . '</a></p>';
   	}
   	return $child_excerpt;
    }
   
   add_filter('wp_trim_excerpt', 'all_excerpts_get_more_link');

   my function does a couple other things, but hopefully you get the idea

   "Continue Reading"

   Is there a away to set a custom field and so that a custom anchor text to be used instead of "Continue Reading", for SEO reasons? Thanks.

   You can use get_post_meta to set a variable with the post's custom field, and insert that into your function: http://codex.wordpress.org/Function_Reference/get_post_meta

   you could also do something like

   $child_excerpt = '<p>' . $post_excerpt . '</p>' . '<p class="readmore">ID) . '">' . 'Continue Reading ' . get_the_title() .'</p>';

   and it would always come back

   "Continue Reading A Post About Bacon"
   "Continue Reading About Why Helga is Awesome"

   etc. :) but i think you could also do what kwight suggested w/ the custom fields. i never use custom fields though as i use WPAlchemy to create custom meta boxes instead. farinspace.com/wpalchemy-metabox/

   and don't the thumbnails come wrapped in a permalink by default these days? can't remember
