iVatar is a free service and an open specification for hosting profile images tied to email or OpenID addresses. It's rewritten from scratch in 2018, when the original author (François Marier1) of libravatar ("Libre Avatar") decided to close the service for various reasons. TODO: Link here.
Inspired by the elegant solution pioneered by Gravatar,
Libravatar takes a federated approach to the problem and allows domain owners to
specify the server that should host images for their organisation.
