A bid to create the world?s largest photographic exhibition is on course to set a new Guinness World Record next month.

People from all over the UK are urged to help break the current record of around 32,000 images by sending in pictures of ?smiles? for a project organised by Hewlett Packard (HP) and children?s charity NCH.

So far more than 20,000 pictures of smiles have been collected – including 5,000 from the recent Glastonbury rock festival.

HP has pledged to give 25p to NCH for each smile displayed at www.hp.com/uk/smile

Images can be uploaded to the website until mid-August. An exhibition of what organisers hope will be the largest number of pictures ever will take place from 26-29 August at the Royal College of Art, Kensington Gore, London SW7.
