    I have piece of code from my template which take thumbnails from cutom field:

    <?php if ( have_posts() ) : while ( have_posts() ) : the_post(); ?>
				<li class="zoom">
					<div><a href="<?php echo get_post_meta($post->ID, "portfolio_big", true);?>" class="thumbnail" rel="group"><img src="<?php echo get_post_meta($post->ID, "portfolio_small", true);?>" alt="" /></a></div>
					<h2><?php the_title(); ?></h2>
				</li>
				<?php endwhile; else: ?>

    i would like to change it to use the post_thumbnail feature an no more customfields.
    post_thumbnail support is added to the functions.php but when I change the code to:

    <?php if ( have_posts() ) : while ( have_posts() ) : the_post(); ?>
				<li class="zoom">
					<div><a href="<?php echo the_post_thumbnail($post->ID, "portfolio_big", true);?>" class="thumbnail" rel="group"><img src="<?php echo the_post_thumbnail($post->ID, "portfolio_small", true);?>" alt="" /></a></div>
					<h2><?php the_title(); ?></h2>
				</li>
				<?php endwhile; else: ?>

    it’s not working, what ist the mistake ?

    I’m not seeing where you register the thumbnail size “portfolio_big”, do you have it registered as a thumbnail size? otherwise you need to use the standard ones; that’s from looking at this with first glance.

    i have added this:

    add_theme_support( 'post-thumbnails' );
set_post_thumbnail_size(150, 100, true);
add_image_size( 'indexpic', 966, 260, true );
add_image_size( 'portfolio_big', 966, 260, true );
add_image_size( 'portfolio_small', 452, 177, true );

    in functions.php onside the theme folder

    <img src="<?php echo the_post_thumbnail($post->ID, "portfolio_small", true);?>" alt="" />

    ‘the_post_thumbnail()’ creates its own img tag:

    http://codex.wordpress.org/Function_Reference/the_post_thumbnail

    so, the above code should be:

    <?php echo the_post_thumbnail($post->ID, "portfolio_small", true);?>
