I’m replying for others if you are looking for this solution as I found something related to that (It seems that I didn’t search enough…)

Then this is my “updated” code:

<?php global $post;
$rand_posts = get_posts('numberposts=6&orderby=rand');
foreach( $rand_posts as $post ) : ?>
<a href="<?php the_permalink($page->ID) ?>" title="<?php the_title(); ?>">
<?php echo get_the_post_thumbnail($post->ID, 'thumbnail'); ?></a>

<?php endforeach; ?>

Now, I have to update some of my post thumbnails and find a way to add a default thumbnail when the post don’t have image or exclude the posts which doesn’t have thumbnails.
