Around the World in Seven Days - the 3rd Firefox browser campaign, for spreading Firefox. They want 1,000 Firefox related photos (something you have done to help spread the word - i.e. handing out flyers, distributing CD's, car stickers, posters etc) submitted after 7 days. Check out the Mozilla store for Mozilla/Firefox related things (T-Shirts, CD's, stickers)
Update: Photo's needed are not computer related (you or someone you know at a desktop/laptop PC) - they are ways of spreading Firefox, in the Office, street, College etc.
