WordPress Plugins Repository has a brand new plugin for displaying your website user avatars/gravatars in a beautiful grid view. The plugin is much different and more powerful than other avatar widget plugins. With this new plugin you can customize the default gravatar display size, you can choose what user roles to show or you can simply set it to display all users from all roles, the plugin also lets you exclude those user avatars who don’t have any published post.
I already discussed about WordPress hacks for adding custom default avatar in WordPress-BuddyPress Sites. Now I am telling a quick and easy option of using plugin. Kailey Lampert‘s free WordPress plugin simply allows you to change default WordPress avatar i.e. Mystery Man to something else, may be your site’s logo etc.
Some people don’t use Gravatar, some don’t use Twitter and there are some who don’t use Facebook also and when they leave comment on your blog they leave a mystery man image (or your site’s default avatar) in their comment which sometimes does’t look nice. But you can allow them to choose their comment avatars manually by selecting a avatar from their social profile, email or choosing it from a list of your site’s custom avatars. I know about few plugins that allows you to do so.
UPDATE: NOW JETPACK BY WORDPRESS.COM PLUGIN ALREADY PROVIDES YOU OFFICIAL WORDPRESS.COM LIKES MODULE SO THERE IS NO NEED OF USING THIS PLUGIN.
You might have noticed a content like feature at the bottom of most WordPress.com’s blog posts. There is a “Like” button, which when clicked, displays a Gravatar image of the bloggers who liked that post. JetPack by WordPress doesn’t provide you with this feature but still you can have it for your self hosted WordPress blog.
Add some image services in your WordPress site discussions. Add a step between “no gravatar account” and “default gravatar sent back”. Make comments system automatically search and set the commenter’s image.
