Abstract
In this paper, we put forward a technique for keeping web pages up-to-date, later used by search engine to serve the end user queries. A major part of the Web is dynamic and hence, a need arises to constantly update the changed web documents in search engine’s repository. In this paper we used the client-server architecture for crawling the web and propose a technique for detecting changes in web page based on the content of the images present if any in web documents. Once it is being identified that the image embedded in the web document is changed then the previous copy of the web document present in the search engine’s database/repository is replaced with the changed one.
