Big slide settings on the top of homepage

There are currently something like 15 blog posts, so it’s not the case that there are no articles to show after the infinite load is over.

I have limited the post to 2 precisely to avoid showing articles using small thumbs and titles – we would like all articles to be shown with large thumbs (as with the first two). That is the main problem. Is there a way to have every post shown with large thumbs and complete texts?
