Hi vbk100,
we have released a new version which will enables you to control how avatars are shown in your word-press installation.
After you install this new-version:
a) You will see a new option 'Accessibility Settings ->Profile Picture/Avatar Comes From' on plugin settings page. you can go for one of 2 options to change avatar display.
- If you choose 'Authenticating Provider', then profile pic/avatar will be same as your picture on your authenticating provider. e.g you FB profile picture will be displayed, if you are logged in with FB.
- If you choose 'Gravatar', then hen profile pic/avatar will come from gravatar.com; if you do not have a account there, no image logo will be shown.
Hope that adds some value to this plugin for you, keep enjoying :)
