Someone recently sent me an email asking me the following question, and I thought I would share the answer here.
“I’m hoping you can point me in the right direction about where to look to change my thumbnail picture that auto fills on one of your client’s WordPress blog when I post a response?”
Sidenote: This is one part of a series of articles providing basic instructions for using WordPress. To start at the beginning, or view the full index of articles in this series, go to A Simple WordPress User Guide for Beginners.

Those images are called avatars, and on a website powered by WordPress, you assign a photo to your email address by going to http://en.gravatar.com/. There you can assign an image to your email address, or assign multiple images to different email addresses if you have several email address, like I do. Since WordPress powers more websites than any other platform in the world right now, that is a lot of website blogs.
It is pretty quick to set-up and sometimes takes a little time for your gravatar to show up, but it should within 2 or 3 days from my experience. I also recommend using a .png image file over a .jpg as I had issues with JPGs when I was last adding images, but that may have changed by now. Not a big deal, just a preference.
If that helped, or you have something to add to my explanation, please share below, and see if your gravatar shows up.
