The newest version offers you five different ways to view images:
Latest Images, Featured Photos, Categories, Editor's choice and top rated.
Then of course there is the ' Search the site' option at the top left, where you can search via user name, camera type, topic etc.
We don't want to restrict users on how many uploads they make to their own gallery. Some people don't have time to upload daily / weekly and prefer to do it in batches.
