Image thumbnails

You can do it by ‘hand’ too:

<?php
$images = get_children(
array(
	'post_parent' => $post->ID,
	'post_status' => 'inherit',
	'post_type' => 'attachment',
	'post_mime_type' => 'image',
	'order' => 'ASC',
	'orderby' => 'menu_order'
	)
);

if ( $images ) {
foreach ( $images as $id => $image ) {
	$img = wp_get_attachment_thumb_url( $image->ID );
	$link = get_permalink( $post->ID );
	print "\n\n" . '<div><a href="' . $link . '"><img src="' . $img . '" alt="" /></div>';
}
}
?>

Thanks that is what I was looking for. I have seen some very nice themes that for some reason make the poster add custom tags rather then just resize the image. This just makes more sense.

Yes, I understand they want to add flexibility and the custom fields gives you that option, but like about – just check for fields first and if not – resize

Notice one thing missing – I accidently loaded a gallery of images into a post, removed the gallery tag but the images were still there – this method pulls all the images in a post. I think for post image thubnails in themes people would probably just need the first image

Opps…
Forget that part.
This should pick the first image sorted by menu order:

<?php
$images = get_children(
array(
	'post_parent' => $post->ID,
	'post_status' => 'inherit',
	'post_type' => 'attachment',
	'post_mime_type' => 'image',
	'order' => 'ASC',
	'orderby' => 'menu_order'
	)
);

if ( $images ) {
$count = 1;
foreach ( $images as $id => $image ) {
	if( $count === 1 ) {
		$img = wp_get_attachment_thumb_url( $image->ID );
		$link = get_permalink( $post->ID );
		print "\n\n" . '<div><a href="' . $link . '"><img src="' . $img . '" alt="" /></div>';
	}
	$count++;
}
}
?>

mfields, you rock! Thanks a lot!

since wordpress 2.6.2 thumbnails are handled automatically without need of plugins. you just need to go to settings and set the thumb size.

Cool, but how do we grab the medium image ?
I can’t find documentation on this anywhere.

exactly what i was looking for, thanks a lot mfields! just one more thing, what if we want to retrieve embeded post video in the same way as pictures thumbnails and also should be good to add alt=”” tag for thumbnails may you help with that please?!

@mfields

You have an unclosed anchor tag in your template code. The print line should look like this:

print "\n\n" . '<div><a href="' . $link . '"><img src="' . $img . '" alt="" /></a></div>';

i am new at this and know just enough php to be dangerous.
My magazine theme is SUPPOSED to pull a thumbnail from posts using a custom field. but i can’t figure out why it DOESN’T work as it is supposed to.
If it can’t find an image is plugs the post title in as alternate text…THAT part works fine.
I have read the code above, but i have no idea how to implement it.
Which template do I add this code to?

I have been working on this problem for over a week, and my deadline has sort of passed. can anyone help me? I am obviously inadequate.

hee hee hee…i love it when i ask for help and almost immediately SPY my problem.

thanks for being here.
(i hadn’t understood the usage of the custom field…Mfields explained it well on his site)

I’m trying to make an Archives page which lists all the images attached to each page
(I’m not using posts) and I need each image to link to its respective page.

Haven’t had any luck with the codes I found here on the forum or elsewhere.
Do anyone know how I would go about doing this?

Solved my problem, solution here: How to create a page that presents all post images?
