Get Thumbnails (again…)

Hi,

I’m making this new topic because the question asked in the previous one hasn’t been answered.

As a matter of fact, I don’t know how to show thumbnails of articles in the widget. Plugin author’s answer is pretty elusive, so can someone give me in-depth instructions about that?

Thank you in advance,
