They also get a class depending on the size of the thumbnail being displayed. You can style the output with these CSS selectors: 5. ```line-numbers img.wp-post-image img.attachment-thumbnail img.attachment-medium img.attachment-large img.attachment-full ``` 6. You can also give Post Thumbnails their own class: 7. ```php // Give the Post Thumbnail a class "alignleft". echo get_the_post_thumbnail( $post_id, 'thumbnail', array( 'class' => 'alignleft' ) ); ``` 8.

These image sizes can be configured in the WordPress Administration Media panel under Settings > Media. Themes may also add “post-thumbnail”. This is how you can use these default sizes with `get_the_post_thumbnail()`: 13. ```php // without parameter -> Post Thumbnail (as set by theme using set_post_thumbnail_size()) get_the_post_thumbnail( $post_id ); get_the_post_thumbnail( $post_id, 'thumbnail' ); // Thumbnail (Note: different to Post Thumbnail) get_the_post_thumbnail( $post_id, 'medium' ); // Medium resolution get_the_post_thumbnail( $post_id, 'large' ); // Large resolution get_the_post_thumbnail( $post_id, 'full' ); // Original resolution get_the_post_thumbnail( $post_id, array( 100, 100) ); // Other resolutions ``` 14. Register new image sizes for Post Thumbnails with: `add_image_size()`. To set the default size for Post Thumbnails see: `set_post_thumbnail_size()`. 15.

The following code snippet is useful if someone wish to remove width and height attribute. 34. This function provides `'post_thumbnail_html'` filter before returning the html. 35. ```php add_filter( 'post_thumbnail_html', 'remove_thumbnail_width_height', 10, 5 ); function remove_thumbnail_width_height( $html, $post_id, $post_thumbnail_id, $size, $attr ) { $html = preg_replace( '/(width|height)=\"\d*\"\s/', "", $html ); return $html; } ``` 36.

You can set more than just classes – If you want to optimize your SrcSet values you can do something like this 41. ```php echo get_the_post_thumbnail($post->ID, 'WhateverSize-Large', array('title' => 'WhateverTitle', 'sizes' => '(max-width: 320px) 288px, (max-width: 375px) 343px, (max-width: 425px) 393px, (max-width: 540px) 493px, (max-width: 768px) 320px, (max-width: 999px) 435px, 288px')); ``` 42. etc. 43. Normally in a grid, the srcset can go 100vw – which is sometimes way too big – this method lets you control that. 44. * Great trick! I would otherwise have to use the `wp_calculate_image_sizes` filter– which doesn’t support attributes/extra hints yet (though planned to be released for the near future). * [strarsis](https://profiles.wordpress.org/strarsis/) [5 years ago](https://developer.wordpress.org/reference/functions/get_the_post_thumbnail/#comment-5339) 45.

When specifying a size e.g. `get_the_post_thumbnail(null, [300, 300])`, the image’s proportions are preserved and the width/height are maximum sizes. If the a dimension’s are smaller than specified, then the image returned will be the full size image. 61. Example 1: Your image is 500px (width) by 1000px (height), the image returned will be 150px by 300px. 62. Example 2: Your image is 100px by 100px the the image size returned will be 100px by 100px 63.

Post thumbnails in a listing context are often linked to the content they’re representing. Instead of adding that every time, here is a filter you can add that will do it automatically based on an `$attr` passed in. 68. ```php /** * Link thumbnails to their posts based on attr * * @param $html * @param int $pid * @param int $post_thumbnail_id * @param int $size * @param array $attr * * @return string */ function wpdev_filter_post_thumbnail_html( $html, $pid, $post_thumbnail_id, $size, $attr ) { if ( ! empty( $attr[ 'link_thumbnail' ] ) ) { $html = sprintf( '%s', get_permalink( $pid ), esc_attr( get_the_title( $pid ) ), $html ); } return $html; } add_filter( 'post_thumbnail_html', 'wpdev_filter_post_thumbnail_html', 10, 5 ); ``` 69. Just “add the above to your functions.php file” (there’s probably a better place for it) and use it like this in a template file: 70. ```php 'my-custom-class', // classes 'link_thumbnail' => TRUE, // yes please link my thumbnail ] ); ?> ``` 71.
