This invention is a system and method that enables image viewers to search for information about objects, events or concepts shown or conveyed in an image through a search engine. The system integrates search capability into digital images seamlessly. When viewers of such an image want to search for information about something they see in the image, they can click on it to trigger a search request. Upon receiving a search request, the system will automatically use an appropriate search term to query a search engine. The search results will be displayed as an overlay on the image or in a separate window. Ads that are relevant to the search term are delivered and displayed alongside search results. The system also allows viewers to initiate a search using voice commands. Further, the system resolves ambiguity by allowing viewers to select one of multiple searchable items when necessary.
