The increasing number of digital pictures upload everyday to the web from computers and mobile phones is a big opportunity to create a complete digital archive of our planet but is also creating some problems in finding the right pictures we are looking for.
Google has developed Similar Images, an effective beta service which enables people to find similar images starting from an image search. The search is related to the actual content of the image and not to the tag ore textual description. This feature helps users to find pictures of Paris before their vacation to France instead of some embarassing shots of Paris Hilton.
