Hi Brian,
thanks a lot for your input. The image is placed – well ?? – automatically. But you can filter the entries, which are sent (not send, right ?? ) to the browser.
So I quickly programmed an addon (not really tested though, but it should work), which you might want to use. It replaces all gravatars with a image, you can define.
<?php
/**
* Plugin Name: Gravatar replacer for BDN
* Author: websupporter
* Author URI: https://websupporter.net
* Description: Replaces the standard gravatar with another picture for the desktop notifications
**/
add_filter( 'dn_entries', 'grfbdn_dn_entries' );
function grfbdn_dn_entries( $entries ){
//Define the image URL here
$image_url = 'https://websupporter.net/blog/wp-content/uploads/2015/05/banner-772x250-640x250.png';
foreach( $entries as $key => $val ){
$entries[ $key ]['avatar'] = $image_url;
}
return $entries;
}
?>
Just save this code as a new plugin and replace the image url with the URL you want.
Hope this helps.
