Hi, can I somewhere somehow resize the thumbnails on the archivepages for blogposts?
I’ve tried it with the normal options in the CMS and forced regenerate thumbnails, but nothing happens.
I’ve tried to set the thumbnails in functions.php:
if ( function_exists( ‘add_theme_support’ ) ) {
add_theme_support( ‘post-thumbnails’ );
set_post_thumbnail_size( 700, 150, true );
}
and then forced regenerate thumbnails, and nothing happens.

I actually want them as wide as the archivepage itself, without the sidebar.

Thank you!
Jessy
