Libravatar was designed so that domain owners can choose to host themselves the profile pictures for their domain. For example, an organisation may want to have control over the pictures use for their employees.
There currently exist the following Libravatar image server implementations:
|Name||Description||Administration||Programming language||Support for||Default modes|
|libravatar||The software that runs libravatar.org||web-based||Python||Email, OpenID||404, mm, identicon, monsterid, wavatar, retro|
|Surrogator||very simple avatar server||command line only||PHP||Email, OpenID||404, mm|
|Simple Libravatar service||Quick hack to serve static files||command line only||Shell script||none (always returns a static image)|
The following instructions are about the official libravatar.org software.
Getting the code
We are not currently doing regular releases of the code, but you can easily get the latest copy from our git repository:
git clone git://gitorious.org/libravatar/libravatar.git
Once you've got a copy of the code, follow the instructions in the INSTALL file.
A number of options can be customised in the libravatar/settings.py file. If there's anything that's unclear in there, please file a bug against the project so that we know how to improve the documentation.
Once your instance is running on a publicly-accessible server (avatars.example.com in this example), add the following records to your DNS zone file:
_avatars._tcp.example.com. IN SRV 0 0 80 avatars.example.com _avatars-sec._tcp.example.com. IN SRV 0 0 443 avatars.example.com
The first entry (_avatars._tcp) should point to an HTTP server whereas the second one (_avatars-sec._tcp) is for an HTTPS server (if you have one).
The time-to-live (cache expiry) should be set to at least 1 day (86400 seconds).
If you choose a TTL smaller than 1 day, Libravatar clients are allowed (and encouraged) to ignore it and cache your entry for a day.
If you use full hostnames or subdomains in your email addresses, for example email@example.com and firstname.lastname@example.org, then you need to have a set of SRV records for each of them:
_avatars._tcp.foo.example.com. IN SRV 0 0 80 avatars.example.com _avatars-sec._tcp.foo.example.com. IN SRV 0 0 443 avatars.example.com _avatars._tcp.bar.example.com. IN SRV 0 0 80 avatars.example.com _avatars-sec._tcp.bar.example.com. IN SRV 0 0 443 avatars.example.com
SRV weights and priorities (optional)
All SRV entries should have the same priority. Lower priority ones will be ignored by Libravatar clients.
You may however use weights to spread the load across more than one avatar server.
Once you have these records, have a look at the domain check tool to make sure everything is working.
