Method for highlighting regions or images within an html document that have or haven't changed since those regions or images where last down loaded Currently when a website is displayed in a browser the user is not notified as to which images or regions of the website have changed since it was lasted viewed. There are products that save a comparison page to show the differences; however those products require having two copies of the site stored. Most users would interested not so much as to the specific of the change but more of a quick scan of the site to see which information is new. Web browser often cache websites. The browsers cache would be a starting point for determining if an image has changed as the cache is updated. The history of the cache changes would be used to track the images or regions that are no longer in the cache and keep the time stamp of when the changed occurred since the last down load. As part of this, the author of a web page could indicate automatically via a web page editor the change history.
