Pagination is unlikely to work on anything which is not the main query and there is not much point to try to force it to work in other places.

Then just pass the thumbnail value into the second parameter of previous_post_link(). $prevPost = get_previous_post(); $prevThumbnail = get_the_post_thumbnail( $prevPost->ID ); previous_post_link( ‘%link’, $prevThumbnail );
