This plugin makes it easy to display lists of user avatars, grouped by user roles, on your (multiuser) site. It also allows you to insert single avatars for blog users or any email address into a post or page – great for displaying an image of someone you’re talking about.
It makes use of built-in WordPress (core) functions to retrieve user information and get avatars.
Integrates with: Gutenberg, BuddyPress, xprofile, Multisite, Wpmu, BBPress, co-authors.
Avatar lists can be inserted into your sidebar by adding a widget or into posts/pages by using a <a href="http://authoravatars.wordpress.com/documentation/authoravatars-shortcode/" rel="nofollow ugc">shortcode</a>. The plugin comes with a tinymce editor plugin which makes inserting shortcodes very easy.
This also provides Gutenberg Block for use with the Gutenberg editor. 
Please help with the plugin Translations at https://translate.wordpress.org/projects/wp-plugins/author-avatars.
Both the shortcode and widget and Gutenberg Block can be configured to:
<ul>
<li>Show a custom title (widget only)</li>
<li>Only show specific user groups and/or hide certain users</li>
<li>Limit the number of users shown</li>
<li>Change the sort order of users or show in random order</li>
<li>Adjust the size of user avatars</li>
<li>Optionally show a user’s name or biography</li>
<li>Show users from the current blog, all blogs or a selection of blogs (on WPMU/Multisite)</li>
<li>Group users by their blog (when showing from multiple blogs), and show the blog name above each grouping.</li>
<li>Support users from Co-Author Plus, Ultimate Member, BBpress and BuddyPress (xprofile)</li>
<li>Limit the number of avatars per page for large sets by adding a page_size to the shortcode e.g. “page_size=30” (shortcode only)</li>
</ul>
Additionally, single user avatars can be inserted using the <a href="http://authoravatars.wordpress.com/documentation/show_avatar-shortcode/" rel="nofollow ugc">show_avatar shortcode</a> and configured to:
<ul>
