How to insert thumbnails into external php page

Hello,

How can I insert the latest posts (as thumbnails only) without using wp-blog-header.php . Something like pure sql injection.
wp-blog-header.php crashed after the last update, See my post: https://www.ads-software.com/support/topic/wp-blog-headerphp-problem-in-external-html

Here is a custom code for insert titles only.

<?php
//connect to the database
mysql_connect($dbhost, $dbuser, $dbpassword);
@mysql_select_db($dbName) or die("Unable to select database");

//get data from database -- !IMPORTANT, the "LIMIT 5" means how many posts will appear. Change the 5 to any whole number.
$query = "Select * FROM wp_posts WHERE post_type='post' AND post_status='publish' AND ID IN (SELECT object_id FROM wp_term_relationships WHERE term_taxonomy_id = 10) ORDER BY post_date DESC LIMIT 5";  //insert post taxonomies

$query_result = mysql_query($query);
$num_rows = mysql_numrows($query_result);

//close database connection
mysql_close();

for($i=0; $i< $num_rows; $i++){
$blog_date = mysql_result($query_result, $i, "post_date");
$blog_title = mysql_result($query_result, $i, "post_title");
$blog_content = mysql_result($query_result, $i, "post_content");
$blog_permalink = mysql_result($query_result, $i, "guid");
$blog_date = strtotime($blog_date);
$blog_date = strftime("%b %e", $blog_date);
?>

<a href="<?php echo $blog_permalink; ?>" target="_blank"><?php echo $blog_date; ?>: <?php echo $blog_title; ?></a>

<?php
}
?>
