Author Spotlight widget displays the profile of the author(s) with Social links (example: Twitter, Facebook) and his/her profile picture or Gravatar on any post or page that has an Author. The widget automatically detects the current author(s) of the displayed post or page; just drag and drop the widget on your sidebar and you are done.
To display a custom photograph with the Author’s Profile you may install the <a href="https://wordpress.org/extend/plugins/user-photo/" title="User Photo WordPress plugin" rel="ugc">User Photo</a>. In absence of this plugin the widget will fall-back to displaying the Gravatar associated with the user. If your posts have multiple authors you may use the <a href="https://wordpress.org/extend/plugins/co-authors-plus/" title="Co-Authors Plus WordPress plugin" rel="ugc">Co-Authors Plus</a>, the Author Spotlight will then display all the author profiles one below another for such post/page.
Note that installing the User Photo or Co-Author plugin is purely optional, this widget will work fine without them as well.
If you face any issues with the plugin or have any suggestion/feature requests please do so <a href="https://wordpress.org/tags/author-profile" title="Author Spotlight plugin support forum" rel="ugc">at the support forum</a>.
