Messenger

Hi,

To change the sharing link from page URL to image URL please try to use the following code snippet:

add_action('wp_footer', 'my_wp_footer2');
function my_wp_footer2() { ?>
    <script>
        window.addEventListener('load', function() {
            function sti_data( data ) {
                if ( data.network === 'messenger' ) {
                    data.page = data.media;
                }
                return data;
            }
            if ( typeof StiHooks === 'object' && typeof StiHooks.add_filter === 'function' ) {
                StiHooks.add_filter( 'sti_data', sti_data );
            }
        }, false);
    </script>
<?php }

Add this code inside your theme functions.php file or just use some code snippets plugin.

Regards

Did you see an image when sharing to Messenger before applying that custom code?

For Messager you shouldn’t see the image itself. But when sharing it must be attached to the message like when you share the links to some sites.
