A showcase of more than 33,000 photographs has set a new Guinness World Record for the largest photographic exhibition, shattering the previous record of 32,169 images.
The exhibition, on at the Royal College of Art in London until Monday, is made up of pictures of people smiling in a project organised by Hewlett Packard (HP) and the children?s charity NCH.
People from all over the UK were invited to send in their pictures to HP?s website, with the company pledging to donate 25p to NCH for each picture ? raising thousands of pounds for the charity.
Celebrities taking part included TV presenters Dermot Murnaghan and Sian Lloyd.
People can still contribute to the project, with cameras and photo printers on hand at the Royal College of Art to allow visitors to capture, print and exhibit their pictures.
People from Hull in East Yorkshire ? a city recently branded the worst place to live in the UK by a Channel 4 television programme ? contributed the most smiles to the record attempt (2,300).
?This record proves that British people are still great smilers, no matter what. Hopefully, the British smile will become as famous as the British stiff upper lip,? said Ian Whittaker, HP?s vice president for the Imaging and Printing Group in UK & Ireland.
The previous record was held by Unilever in Sri Lanka.
The HP Smile show ? which contains the largest number of pictures ever for an exhibition ? is on until 29 August at Royal College of Art, Kensington Gore, London SW7. It is open from 10am-5pm. Tel: 020 7590 4444.
? Last night the official record stood at 33,401 images but this may rise over the weekend if more people contribute their pictures. Organisers will then be able to apply for a new record.
