Latest 3 blog articles (Freemarker)

Thank you for this excellent documentation and code sample for displaying the latest three blog entries from the community in a custom component.

I have taken this and added it to our community and it is working well, however I would like to make it display like the Lithosphere version, which includes a teaser image on the left, then the title and teaser in the middle and all the way to the right is the friendly date, the author name and a tiny thumbnail of the author.

Here is a snapshot of the Lithosphere recent blog articles captured from the home page of the community today.  What I would like to know is where to the teaser images come from?  Are they coming from a special location, or are they simply included in the teaser of the blog by policy?

I would also like to know where to get the tiny thumbnails for the author are found.  Are they standard or custom?

Thanks again for the great post.
