Great, you’re welcome :-).
Btw, you can remove step 1 because this code is already part of the theme (check library > siteframework).
Do all your blog posts have featured image? If not, then I should adjust code of step 2 a bit since the border around the pic is still displayed.
If you have some spare time, I appreciate it if you review one of my Themes or Plugin on WordPress.org: http://profiles.wordpress.org/guido07111975
