@Agolf Cartson: The count is only here to make sure we don’t try to display pics that doesn’t exists. If there’s one or more pics in the post content, the pics are displayed, otherwise nothing is shown.
In this code, the pictures are simply displayed, but you could easily modify it to create a gallery or something like this

Imagine your blog have 150 posts. How can you remember that post #29 that you wrote one year ago, have a picture or not? Counting make WP doing that job for you

There is another way to echo an image that may be in a post.

ID;
$the_content =$wpdb->get_var("SELECT post_content FROM $wpdb->posts WHERE ID = $id");
$home = get_option('home');
$pattern = '!

I wrote an article about this on my site: WPCult

So what would be the difference between the two?

there’s a easier way to do so, just by getting the first image attached to a post, like so:

function get_first_attachment() {
global $post;

if ( $output != ” )
return ”;

$id = $post->ID;
$attachments = get_children( array(‘post_parent’ => $id, ‘post_status’ => ‘inherit’, ‘post_type’ => ‘attachment’, ‘post_mime_type’ => ‘image’, ‘order’ => ‘DESC’, ‘orderby’ => ‘menu_order ASC’) );
$tpl = get_bloginfo(‘template_url’);
$nothing = $tpl.’/nothing.jpg’;

if ( empty($attachments) )
return $nothing;

$output = “\n”;
foreach ( $attachments as $id => $attachment )
$link = wp_get_attachment_url($id);
return $link;

}

you have to put a nothing.jpg in your template folder,

if you attach an image in your post, it will return the image link, else will return the nothing.jpg (you have to put a nothing.jpg in your template folder),

simply apply inside the loop,

I’m impressed you really know how to handle PHP Codes with wordpress!
