Congrats (and thanks) to the wordpress team on getting the thumbnail feature onto wordpress, might i ask that the feature be extended so as to allow one to display thumbnails of different sizes?
i.e.
add_theme_support( 'post-thumbnails' );
set_post_thumbnail_size( 203, 120, true ); // size 1
set_post_thumbnail_size_2( 200, 50, true ); // size 2
set_post_thumbnail_size_3( 50, 50, true ); // size 3
or does this already exist and i don't know how to make it work?
