How is a photolog different from a plain old Web page? Many people who have digital cameras find themselves churning out a constant stream of images because it is fun, easy, and cheap to do. Photologs are built to handle that stream, with the newest photos right up front and older ones receding into the background. Traditional online photo galleries lack this chronological structure and can be harder to update. And like Weblogs, many photologs are updated every day, making individual photos less important than the regular flow of images.
