Many thanks to the photographers for allowing us to use their images via Flickr: Londonshouts UK, Stephanie Sadler, World of Tim, psyxjaw, unslugged, Pangaia (en vela), ChrisKenchPhotography.com, Andrew Smith and Natalie Clarke. Plus Mehrdad Aref-Adib, who created the London Eye image back in 2006.
