Add thumbnail in home page without plugins

I use this in my Get the Image plugin:

<?php

global $post;
$default_size = 'thumbnail';

$attachments = get_children( array('post_parent' => $post->ID, 'post_status' => 'inherit', 'post_type' => 'attachment', 'post_mime_type' => 'image', 'order' => 'ASC', 'orderby' => 'menu_order ID', 'numberposts' => 1) );
if($attachments) :
	foreach($attachments as $id => $attachment) :
		$img = wp_get_attachment_image_src($id, $default_size);
	endforeach;
endif;
?>

This should return you a variable of $img, which is the thumbnail URL of the first image (ordered in media uploader). This should be within the Loop.

There are no template tags for something like this.

hello Greenshady,
thanks for your quick reply. just tested but not working, no images showing up in the homepage…

Sorry, meant to say the img URL would be $img[0] and not $img as I said before.

Using that works perfectly.

Hello greenshady, just tested, it echoes just the blog main address, with no images attached.

this is the code I’m using:

<?php

global $post;
$default_size = 'thumbnail';

$attachments = get_children( array('post_parent' => $post->ID, 'post_status' => 'inherit', 'post_type' => 'attachment', 'post_mime_type' => 'image', 'order' => 'ASC', 'orderby' => 'menu_order ID', 'numberposts' => 1) );
if($attachments) :
foreach($attachments as $id => $attachment) :
$img[0] = wp_get_attachment_image_src($id, $default_size);
endforeach;
endif;
?>

is there any hack I’ve to do with it?

Note:
$default_size = ‘thumbnail’;
$default_size = ‘medium’;
$default_size = ‘full’;

for the ‘full’ size, the max width is 500 and if you want to change this insert next line :
$GLOBALS[‘content_width’] = ‘your full size’;

Thanks Justin! Just what I needed.

I know this is a very old post, but for the benefit of others, you put Justin’s code within the loop as is. Then to call the thumbnail, use.

<?php if (!$img[0]) { echo 'Default image'; } else { ?><img src="<?php echo $img[0]; ?>" /><?php } ?><?php the_excerpt() ; ?>

You will see that I have an additional if else condition to check to see if the post does have attachments and display a default.
