I follow the link - definitelly isn't Suffusion there but now I understand that is just an example site. That theme don't use thumbnails and excerpts, are full images centered after titles. Probably this look is obtained by displaying full posts but with "read more" tag for some posts (others are in full format without any doubt).
Excerpts with thumbnails, exactly like in Suffusion are the 2 little posts after the "Google Play Music....", and some others, below on the page, with the same look.
Can also try to use a plugin like TinyMCE Excerpts to format manual excerpts in that way (this last ideea will works only if wordpress don't strip <img> tags even in manual excerpts).
