No, the_post_thumbnail no la tienes que declarar en el functions.php.
Cómo se muestran los posts? cuantos por renglón? uno por renglón o usas formato grid (2,3 o más)?
Veo que en tu código hay una función <?php dynamicnews_display_thumbnail_index(); ?> esa sí checa que hace en el functions.php, le da un tamaño?
No he entendido lo de los renglones. En la home aparece un fragmento de los últimos posts, no sé si es eso a lo que te refieres.
En el functions.php no le da ningún tamaño, te lo pego tal cual porque llevo tantas semanas con esto que estoy desesperada:
