Image size of pinned post on Blog

Hi there,

It may be possible, but you'll need to use the Media Attachment Size option in the Customizer instead of the custom width/height controls.

First, I would create two new image sizes - one for the main posts and one for the featured post: https://docs.generatepress.com/article/adding-image-sizes/

After you add them, regenerate your thumbnails and set your Media Attachment Size option to the size for your main posts: https://docs.generatepress.com/article/adjusting-the-featured-images/

Then, you might be able to do this:

add_filter( 'generate_page_header_default_size', function( $size ) {
    $classes = get_post_class();

    if ( in_array( 'featured-column', $classes ) ) {
        return 'your-featured-image-size-name';
    }

    return $size;
}, 20 );

Worked perfectly, thank you so much!

You're welcome :)
