Here’s what we want… our headshot and a little about us, biography blurb at the bottom of each post. You can add this for multiple users who may be blog authors on your site.
1. Go to your users section of your WordPress dashboard.
2. Click to edit the user of your choice.
3. Scroll down to see the area for biographical information. Add your little author / about blurb here. It will now appear under each post that user has authored.
4. The image displayed with the selected user is associated with the user’s email address. It’s called your gravatar. To change it in WordPress, see here.
