Use higher res image in search result

I hope you are well today and thank you for your question.

Could you please share the page URL from your site where it is displaying so that I can help you?

Best regards,

For some reason this was marked as resolved, but I would still like to know if there’s a way to use a higher res image in the search results.

You didn’t answer my previous question but now I saw that you have added the URL in your initial reply.

I can see you are using the AJAX search results and you can change the image size in the search results by using the plugin is_ajax_image_size filter hook which is added in the below plugin function.

	function image_markup( $field, $post ) {
		$image = '';
        $image_size = apply_filters( 'is_ajax_image_size', 'thumbnail' );
		$temp_id = 0;
		if ( 'product' === $post->post_type ) {
			$_product = wc_get_product( $post );
			$temp_id = $_product->get_id();	
		} else {
			$temp_id = $post->ID;	
		} 
		if( 'attachment' === $post->post_type ) {
			$image = wp_get_attachment_image( $temp_id, $image_size );
		} else if( has_post_thumbnail( $temp_id) ) {
			$image = get_the_post_thumbnail( $temp_id, $image_size );
		}
		$is_markup = apply_filters( 'is_customize_image_markup', false );
		if ( $is_markup ) {
			do_action( 'is_image_markup', $image, $field );
		} else if ( isset( $field['show_image'] ) && $field['show_image'] ) { ?>
                    <div class="left-section">
                        <div class="thumbnail">
                            <a href="<?php echo get_the_permalink( $temp_id ); ?>"><?php echo $image; ?></a>
                        </div>
                    </div>
		<?php }
	}
