We've ditched the cropped image thumbnails throughout the site, yay! We had a vision for how the new site could be improved which involved much larger images, even in the galleries. Cropping the thumbnails gave us larger images, but as those of you who got in contact pointed out, it just wasn't working in practice and the cropping caused problems.
Thanks to the people who emailed us, we got a valuable opinion from our users and were able to improve the site. Please do continue to contact us, we are listening!
