WordPress has many useful plugins to increase author and user interaction. Having a good author profile page is one of them. One of the most important part of the author page is author’s profile photo, so users can associate a picture with them. User Photo plugin allows a user to associate a profile photo with their account through their “Your Profile” page. Admins may add a user profile photo by accessing the “Edit User” page. Uploaded images are resized to fit the dimensions specified on the options page. A thumbnail image correspondingly is also generated. User photos may be displayed within a post or a comment to help identify the author. To see the documentations on how to implement this plugin, see the WordPress Plugin page.
