Highend 'One-page' Portfolio items not adhering to grid

Hi there,

I’ve been customising http://www.onefilms.co using the ‘One Page’ template. I noticed when I began that the images didn’t line up, but it’s only now that I realise that there may be something wrong with my install.

The images in the portfolio section and in the footer widget are not adhering the grid. They don’t seem to be cropping as they do in the online demo: http://hb-themes.com/themes/highend_wp/one-page/
