images that appear in content are often of low quality , so there may be reason to provide higher quality images to a user . when content , such as a web page , is detected as having an image , a system may generate a query that can be used to retrieve the image from a search engine . the query also causes the search engine to identify other images , which , since they satisfy the query , may be similar to the original image . an interface may be presented to the user that presents these alternative images . in this way , the user can be shown images that are similar to that which the original content author wanted the user to see , but where the additional images may be of higher quality .
