    19 WP First Letter Avatar **sets custom avatars for users without Gravatar**. The avatar will be a first letter of the users's name, just like in [Discourse](http://www.discourse.org/). You can also configure plugin to use any other letter to set custom avatar.

    2020
    2121WP First Letter Avatar includes a set of **beautiful, colorful letter avatars** in many sizes. Optimal size will be chosen by the plugin in order to display high quality avatar and not download, for example, big 512px avatars when only 48px is needed... **PSD template** for avatar is also included.
    … …  
    2929All images were compressed using the fantastic [TinyPNG](https://tinypng.com/), so avatars are **incredibly light and ultra-high quality**.
