Fotolog is the world's leading photo-blogging and social networking website. With over 23 million registered users, it is one of the oldest and largest sites for sharing pictures through online photo diaries or photo blogs. The website offers both free and subscription accounts. The free version is ad-supported, and limits users to uploading one picture per day, and having only 20 comments (in their "guestbook"). The free user can also customize their page and add other fotologs into their "Friends/Favorites" list. Paying members, known as "Gold Camera patrons" can upload up to 6 pictures a day, have 200 comments per photo and can access better customer support. Recent changes mean that Gold Cam members can comment on any guestbook that is full. Other new features include customized photo-headings, and having the most recent image appear beside the members name when commenting on other photoblogs.
