I’ve just found a way round it.

When I’d specifically created a 150px square image for the main post thumbnail and uploaded it; WP uses that 150px x 150px image to make the new thumbnail. Where I’d chosen an image of another size from the media library and used the 150px square version that it created for the main thumbnail; WP uses the original image from the media library to make the new sized thumbnail which is why they came in all shapes and sizes.

So I have just made sure that the last few posts have proper specifically uploaded square thumbnails and that makes the secondary size of thumbnails square.

Confused? I am.

Thank you, SteelFrog.

I’m having trouble implementing it on my custom page. I’ve put this after the loop which I’ve adapted from a bit of PHP from my sidebar that lists my last 10 posts.

It doesn’t show the thumbnails and has the permalinks and titles wrong – it returns the permalink (?n – not pretty) and title of the page you are on.

<ul>
<?php
$myposts = get_posts('numberposts=10');
foreach($myposts as $post) :
?>
<li> <?php the_post_thumbnail('my_thumbnail'); ?> <a href="<?php the_permalink(); ?>"><?php the_title();?></a></li>
<?php endforeach; ?>
</ul>

And when I put it in the sidebar the list of posts are OK but the new thumbnails are all of the post you are on rather than the post it is next to in the list.

It looks like the thumbnail call should have the post id on it?

Well done, RV, you’re way ahead of me. I’ve spent many hours with my nose in the codex without getting so much as a sniff!

Thanks again 🙂

I’ve tried that and a few other things – maybe you just can’t have PHP inside an echo?

Thanks for trying

Thanks RVoodoo, I don’t believe I missed that as I was reading Justin Tadlock’s piece. It would be great now if I could find away of linking the default thumbnail image. I’ve tried:

<?php
        if ( has_post_thumbnail() )
                the_post_thumbnail(array(150, 150));
        else
                echo '<a href="<?php the_permalink(); ?>" title="<?php the_title(); ?>"> <img src="/images/default-thumbnail.jpg" alt="Default Thumbnail" /> </a>';
?>

But it didn’t work.

I did tell you I was thick. There was a problem in the sidebar. To list the posts I’d put this:

<?php query_posts('showposts=5'); ?>
<ul>
  <?php while (have_posts()) : the_post(); ?>
  <li><a href="<?php the_permalink() ?>"><?php the_title(); ?></a></li>
  <?php endwhile;?>
</ul>

I don’t know where I’d got that from. But it looks wrong. It’s opened a loop without closing it?

I’ve just substituted it for this

<ul> <?php wp_get_archives('title_li=&type=postbypost&limit=10'); ?> </ul>

and now it works.

I’m sorry, I hadn’t thought that something in the sidebar could affect single.php and archive.php like that. This is a result of not knowing much, just getting bits and bobs from everywhere and putting them together hoping they’ll work.

Thank you for this. It was interesting to see your problem-solving process but I really apologize for not thinking of this stupid bit of code I’d put in the sidebar.
