Image search (or image search engine) is a search engine specialised on finding pictures, images, animations etc. Like the text search, image search is an information retrieval system designed to help to find information on the Internet and it allows the user to look for images etc. using keywords or search phrases and to receive a set of thumbnail images, sorted by relevancy.
Specialized search engines, like in the fields of image search, are among the fastest growing search services on the internet. In 2005 alone the number of image searches increased by 91% (Nielsen/NetRatings 2006-03-31).
Many of the sites that today offer image search uses a service powered by one of the big three; Google, Picsearch or Yahoo.
History
The very first image search service on the Internet was Ditto, a small scale image search. In the summer of 2001 both Picsearch and Google launched large scale image search engines. This was a revolution to the search industry. The user had previously been left with only one choice of finding information; the text search engines. Since so much information on the Internet is visual, and the human brain is well suited to quickly deal with visual information, the success was given.)
Google image search.
In addition to their own website, Google offers their image search service to license customers such as other search engines and portals to enable them to complete their own search package. Google image search is today one of the world's largest providers of image search.
Picsearch
The newcomer Picsearch was founded in 2000, and built their business entirely on an image search engine, striving to be the world's first large scale image search engine. Launching their image search in the summer of 2001, at the same time as Google, they soon grew popular among the users on the Internet.In addition to their own website, Picsearch offers their image search service to license customers. Picsearch is today one of the world's largest providers of image search, and has published plans to become the world's first carbon free search engine.
Yahoo
Many other companies followed, when Google and Picsearch offered this new tool for retrieving information on the Internet. However the time and cost for developing an own image search technlogy to compete with the existing ones are not always worth while. Some did succeed and Yahoo is today one of the world's largest providers of image search.AltaVista

Retrievr is an experimental system that matches a user-drawn or uploaded image with a sub-set of images from Flickr, a photo-sharing site. Unlike the others above, it uses the distribution of colours and darkness in the image, not words associated with the images.How image search works
A common misunderstanding when it comes to image search is that the technology is based on detecting information in the image itself. But most image search works as other search engines, The metadata of the image is indexed and stored in a large database and when a search query is performed the image search engine looks up the index, and queries are matched with the stored information. The results are presented in order of relevancy. The usefulness of an image search engine depends on the relevance of the results it returns, and the ranking algorithms are one of the keys to becoming a big player.When performing a search the user receives a set of thumbnail images, sorted by relevancy. Each thumbnail is a link back to the original web site where that image is located. Using an advanced search option the user can typically adjust the search criteria to fit their own needs, choosing to search only images or animations, color or black&white, and setting preferences on image size.
