   I have a frustrating question to ask, it's taking me aaages to find an answer through Google. The concept is deceivingly simply yet the execution seems like a nightmare!! I’m sure someone who has more programming brains than I do figured out a solution…please share your brilliance with a poor soul.

   In my archive,
   I would like a thumbnail of the posts images for each archive post. Does anyone know the php query to call up the image?

   I was thinking it would be something like ;

   the_title();

   ie the_image();

   so for each entry on the archive, it would call up a thumbnail to the list.

   Thanks for having a think for me!

   one alternative solution is you can call the thumbnail 'manually' like i did:
   

   <ul id="archivelist">
   		<?php while (have_posts()) : the_post(); ?>
   
   			<li class="title"><a href="<?php the_permalink();?>">
   			<img src="http://www.example.com/images/thumb-<?php echo $post->post_name;?>.jpg" alt="<?php the_title();?>"/>
   			<span class="archivetitle"><?php the_title();?></span><small><strong>Category:</strong> <?php
   foreach((get_the_category()) as $cat) {
   echo $cat->cat_name . ' ';
   } ?><?php the_time('F j, Y'); ?></small></a></li><?php endwhile; ?>
   			</ul>

   this line: <?php echo $post->post_name;?> will call your slug name. so be sure to name your thumbnail exactly the same with your post slug.

   First, create a function.php file in your theme directory.
   Then paste this into it:
   

   <?php
   function postimage($size=medium,$num=1) {
   	if ( $images = get_children(array(
   		'post_parent' => get_the_ID(),
   		'post_type' => 'attachment',
   		'numberposts' => $num,
   		'post_mime_type' => 'image',)))
   	{
   		foreach( $images as $image ) {
   			$attachmenturl=wp_get_attachment_url($image->ID);
   			$attachmentimage=wp_get_attachment_image( $image->ID, $size );
   
   			echo '<a href="'.$attachmenturl.'" rel="lightbox">'.$attachmentimage.'</a>';
   		}
   	} else {
   		echo "No Image";
   	}
   }
   ?>

   Then,, wherever in the loop you want a post's attached image displayed, put
   

   <?php postimage('thumbnail'); ?>

   If you just insert
   

   <?php postimage(); ?>

   you'll get the newest attached image in full size.

   Mores, I did as you said but I got

   Fatal error: Call to undefined function: postimage() in /home/mysite/public_html/wordpress/wp-content/themes/default/page.php on line 159

   so i copied your function in the functions.php file of my theme, and it works...however I would like this function to call a specific pic from a specific gallery of nextgen gallery...do you think this is possible? I have zero knowledge of php, so maybe this is a simple matter and a nobrainer to you...

   pfft, I dunno. I have no idea how nextgen gallery works.
   What my code does is simply check for all uploads that are attached to the current post.
