# Libravatar Plugin
|
||||
by [Klaus Weidenbach](http://friendica.dszdw.net/profile/klaus)
|
||||
|
||||
This addon allows you to look up an avatar image for new users and contacts at [Libravatar](http://www.libravatar.com). It will be used if there have not been found any other avatar images yet for example through OpenID.
|
||||
|
||||
Libravatar is a free and open replacement for Gravatar. It is a service where people can store an avatar image for their email-addresses. These avatar images can get looked up for example in comment functions, profile pages, etc. on other sites. There exists a central installation at [www.libravatar.com](http://www.libravatar.com), but you can also host it on your own server. If no avatar was found Libravatar will look up at Gravatar as a fallback.
|
||||
There is no rating available, as it is on Gravatar, so all avatar lookups are g-rated. (Suitable for all audiences.)
|
||||
|
||||
PHP >= 5.3 is required for this plugin!
|
||||
|
||||
You can not use the Libravatar and Gravatar addon at the same time. You need to choose one. If you need other ratings than g you better stay with Gravatar, otherwise it is safe to use Libravatar, because it will fall back to Gravatar if nothing was found at Libravatar.

||||

||||
|
||||
# Configuration
|
||||
## Default Avatar Image
|
||||
If no avatar was found for an email Libravatar can create some pseudo-random generated avatars based on an email hash. You can choose between these presets:
|
||||
|
||||
* __MM__: (mystery-man) a static image
|
||||
* __Identicon__: a generated geometric pattern based on email hash
|
||||
* __Monsterid__: a generated 'monster' with different colors, faces, etc. based on email hash
|
||||
* __Wavatar__: faces with different features and backgrounds based on email hash
|
||||
* __Retro__: 8-bit arcade-styled pixelated faces based on email hash
|
||||
|
||||
See examples at [Libravatar][1].
|
||||
|
||||
## Alternative Configuration
|
||||
Open the .htconfig.php file and add "libravatar" to the list of activated addons:
|
||||
|
||||
$a->config['system']['addon'] = "..., libravatar";
|
||||
|
||||
You can add one configuration variable for the addon:
|
||||
|
||||
$a->config['libravatar']['default_avatar'] = "identicon";
