[Plugin: Yet Another Related Posts Plugin] Intresting thing

The new beta 3.4b8 doesn’t work form me – no post related – so i tried version 3.3.3. I wanted to have post with thumbnail in the sidebar – but no way. Only titles are showing.

Hovewer when i put related content automatically on page using thumbnail template – pictures are showing as related posts.
So i suppose there should be sth wrong with the widget.
