I need just the image source of post thumbnails for a js slider I’m trying to integrate.

For example the loop will look like this
```
<img src="thumbnail url" longdesc="URL_1" alt="Text_1" />
<img src="thumbnail url" longdesc="URL_2" alt="Text_2" />
<img src="thumbnail url" longdesc="URL_3" alt="Text_3" />
```
so in the img src I need to somehow echo the post thumbnails url. Can someone please share how to do this .. if possible?

I haven’t tested this, but you might be able to use this (or something like it…):
```
$url = wp_get_attachment_url( get_post_thumbnail_id($post->ID) );
<img src="<?php echo $url; ?>" longdesc="URL_2" alt="Text_2" />
```

Thanks trepmal!

I did try that code, it works but it gets the full size image url. For example,

https://www.website.com/wp-content/uploads/2010/09/AX0480GR2.jpg

the url for the thumbnail would be

https://www.website.com/wp-content/uploads/2010/09/AX0480GR2-300x298.jpg

I can’t find any documentation on how to get the exact URL for the generated thumbnail.. ??

Maybe this then?
```
<?php $thumb = wp_get_attachment_image_src( get_post_thumbnail_id($post->ID), 'thumbnail_size' );
$url = $thumb['0']; ?>
```

Still generates the full size URL

https://www.website.com/wp-content/uploads/2010/09/AX0480GR2.jpg

this is weird. Using the_post_thumbnail(), the URL path is the thumbnail’s but I’m not sure how that’s generated.

oops, I forgot to specificially mention that thumbnail_size should be the name of the thumbnail size you’re using (I think the default is ‘post-thumbnail’?) – did you try swapping that out?

Here is where the the_post_thumbnail() function is defined, you might be able to follow the trail: https://phpxref.com/xref/wordpress/wp-includes/post-thumbnail-template.php.source.html#l40

Trepmal you’re awesome! post-thumbnail works ?? I’ll add the code to my functions, it’s very useful ??

Worked for me, thanks. Below is how I used it in it’s entirety – just in case anyone wants a quick C’nP.
```
<?php query_posts('category_name=Portfolio&order=ASC&orderby=date&posts_per_page=36'); ?>

<?php if (have_posts()) : ?>
<?php while (have_posts()) : the_post(); ?>

<?php
$thumb = wp_get_attachment_image_src( get_post_thumbnail_id($post->ID), 'thumbnail' );
$url = $thumb['0'];
?>
<li><a style="background-image:url(<?=$url?>);" href="<?php the_permalink(); ?>" title="<?php the_title(); ?>"></a></li>

<?php endwhile; ?>
<?php endif; ?>
```

I’ve tried everything I’ve written here and nothing is working for me.

Can one of you help me please?
