Override get_avatar_url()

[aslakr]

Since som plugins use get_avatar_url() to get the url of the avtar, would it be possible to override that?

Example of plugins using get_avatar_url():

I suppose bp_gravatar_url is similar only for BuddyPress, but get_avatar_url() (and get_avatar_data()) was introduced later in WordPress 4.2 (in 2015)?

There are new (pre_)get_avatar_data filters which look perfect for new injection

The same applies when using @pfefferle pfefferle/wordpress-activitypub, i.e. Mastadon will use gravatar instead of federated libravatar.

Do you have any suggestion on how the code should be changed to use the (pre_)get_avatar_data filters?

[pfefferle]

pre_get_avatar_data is what we are using for Webmentions:

• https://github.com/pfefferle/wordpress-webmention/blob/5.X/includes/class-avatar.php#L16
• https://github.com/pfefferle/wordpress-webmention/blob/5.X/includes/class-avatar.php#L161

Anyone care to take over the plugin?
