So I have the beautiful Autofocus theme for my website, but for some reason, half way scrolling down the front page, the images stop being in a 'mosaic' style (i.e stacked together) and instead are one story per row. If you go to the website (www.vikingsinlondon.wordpress.com) and scroll down you'll see what I mean.
I've been trying to figure it out, but can't for the life of me. Any help is really, really appreciated.
The blog I need help with is vikingsinlondon.wordpress.com.
