@pex81: For this you’ll need to create a child theme. You can find more details on creating child theme HERE. Then in your child theme’s functions.php
add the following codes:
function rock_star_archive_content_image() {
$options = rock_star_get_theme_options();
$content_layout = $options['content_layout'];
$archive_top_layout = $options['archive_top_layout'];
if ( has_post_thumbnail() && 'full-content' != $content_layout ) { ?>
<figure class="featured-image">
<a rel="bookmark" href="<?php the_permalink(); ?>">
<?php
if ( 'excerpt-image-left' == $content_layout || 'excerpt-image-right' == $content_layout ) {
the_post_thumbnail( 'rock-star-landscape' );
}
elseif ( 'excerpt-image-top' == $content_layout ) {
if ( 'one-column' == $archive_top_layout ) {
the_post_thumbnail( 'full' );
}
else {
the_post_thumbnail( 'full' );
}
}
?>
</a>
</figure>
<?php
}
}
