Low resolution images on featured slider

Hi,

Unfortunately, there is no available hook or custom code to modify this. If you want to display a custom size for the featured slider only, you will need to edit the template file directly.

Thanks a lot. Applying the code solved my low resolution problem. But I think this affected all of the thumbnails, not only the featured slider images. Via Code Snippet plugin I placed the code to run only on homepage and it slowed down my homepage a bit. Is it possible to apply it "only" to featured slider images? All the other little thumbnails don't need to be in high resolution.

Hi,

You should paste this code into the function.php of the child theme or via the CodeSnippet plugin here: https://wordpress.org/plugins/code-snippets/

function penci_force_full_size_thumbnail($html, $post_id, $post_thumbnail_id, $size, $attr) {
    return wp_get_attachment_image($post_thumbnail_id, 'full', false, $attr);
}
add_filter('post_thumbnail_html', 'penci_force_full_size_thumbnail', 10, 5);

Regards,

I'd appreciate it if you could explain it to me, so I can make the changes by myself. So that other people who have the same issue can also solve their problems.

I'm using featured slider at my homepage. I always upload high resolution images to the featured posts, but on featured slider displayed images are very low quality. I searched for the issue and find a similar thing asked in another theme's support: https://pencidesign.ticksy.com/ticket/3824364

As suggested there, I tried Appearance → Customize → General Options → Manage Image Size then check all the "Disable image size..." options in this section. And clear cache.

But nothing changed. I still have low res images on featured slider
