[Resolved] Always ‘full’ sized featured image shown in archive view

Hi there,

The post list on the site you’ve linked seems to be created within thrive editor (TAR/Thrive Architect).

The theme doesn’t control how the plugin presents the images.

And since Thrive Architect is a third-party plugin outside of our scope of support, I recommend asking them the best practice on how to deal with this. 🙂

Ah I see.

By default, GeneratePress let’s WordPress Core functions handle the serving of the images.

Tom added a filter that may help though, please see this

You can modify the parameters of get_the_post_thumbnail() through the generate_featured_image_output filter.

You can then optimize how WP serves its srcset – example – https://developer.wordpress.org/reference/functions/get_the_post_thumbnail/#comment-2813

Note: Your srcset only has 2 images as opposed to WordPress default (thumbnail, medium, large, full). I’m not sure if this was intended but consider adding more image sizes incase needed.

Hi there,

that is the default behaviour of WordPress – its so as the Browser can select the most appropriate sized image – which when considering Retina / HD devices that image may need to be larger then the one specified.

If you want – you can try using adding this PHP Snippet to stop that from occurring:

function set_max_srcset_width( $max_width ) {
    $max_width = 300;
    return $max_width;
}
add_filter( 'max_srcset_image_width', 'set_max_srcset_width' );

I set the $max_width = 300; which is the default size of the Medium image. If that has been changed in Settings > Media then you should change the above value to match.

That could be the very reason 🙂
Glad we could be of help.
