How to add images from google in search result. I tried put $post->cse_img; in search.php but nothing happened.

search.php

<?php get_header(); ?>

<div id="content">

  <?php if (have_posts()) : ?>
				<h2><?php _e('Search Results For ', 'max-magazine'); ?>&ldquo;<?php echo $s; ?>&rdquo;</h2>
				
				<?php while (have_posts()) : the_post(); ?>			
						
					<div class="post">					
						<div class="post-image">
							<a href="<?php the_permalink(); ?>"><?php the_post_thumbnail( 'thumbnail', array('title' => ""));$post->cse_img;?></a>
						</div>
					
						<div class="right">
				
						<?php if ( is_sticky() ) : ?>
							<div class="sticky"><?php _e( 'Important', 'max-magazine' ); ?></div>
						<?php endif; ?>
					
						<h2> <a href="<?php the_permalink(); ?>" title="<?php printf( __('Permalink to %s', 'max-magazine'), the_title_attribute('echo=0') ); ?>" rel="bookmark"><?php the_title(); ?></a></h2>
					
						<div class="post-meta">						
							<span class="category"><?php the_category(', '); ?></span>
							<?php the_tags( '<span class="sep"> - </span><span class="tags">' . __('Tagged: ', 'max-magazine' ) . ' ', ", ", "</span>" ) ?>	
						</div>								
						
						<div class="exceprt">
							<?php 
								/**
								* the_excerpt() returns first 30 words in the post.
								* length is defined in functions.php.
								*/
								the_excerpt();
							?>
						</div> 
						</div>	<!-- right -->
					</div><!-- post -->
