You can make the thumbnails smal for the archive page if you edit the file content-extensions.php (it is in the folder “structure”).

Here you locate archive loop (attitude_theloop_for_archive) and change featured to featured-medium – like this:

$image .= get_the_post_thumbnail( $post->ID, ‘featured’, array( ‘title’ => esc_attr( $title_attribute ), ‘alt’ => esc_attr( $title_attribute ) ) ).’‘;
$image .= ‘</figure>’;

To this:

$image .= get_the_post_thumbnail( $post->ID, ‘featured-medium’, array( ‘title’ => esc_attr( $title_attribute ), ‘alt’ => esc_attr( $title_attribute ) ) ).’‘;
$image .= ‘</figure>’;

Aftewards you edit your style.css with this:

.post-featured-image {
float: left;
margin-bottom: 30px;
margin-right: 4.67%;
max-width: 700px;
width: 20%;
}
And you will see that the large featured image in the archive page now is a small thumbnail and placed at the left.
