Search system using images
A search system using images is provided in which when a user does not know a relevant URL or search keyword correctly while surfing the Internet, he or she can search a desired website using only an image. The search system using images according to the present invention comprises an image search server and a user terminal. The image search system comprises: an image conversion section for converting the image included in the website information and the to-be-searched image uploaded by the user into search format images; an image search section for comparing eigen values of both the to-be-searched image uploaded by the user and the search image included in the website information and detecting the website information having a matching eigen value; and a storage section for storing the detected website information, the image included in the website information, and information regarding eigen values.

sending information related to the second image.
