Here is an example of a blog entry that displays the users avatar from Gravatar.
To register for Gravatar an upload an image goto: https://en.gravatar.com
If you click on the Avatar you can see the authors profile.
If the author clicks on his avatar then it allows him to edit his profile.
The profile also shows a index to all that authors blog entries. You can click on these to jump to the article.
The Gravatar image is also used in any comments that user makes.
The authors profile and image are shown below the blog entry if you go to the details page by clicking on the blog entry title (in this case Blog Facilities)
A blog entry can include images.
