If you are searching for “notebooks,” use Similar Images to quickly filter images that are either related to notebook computers or paper notebooks. This is also useful when you are trying to find the original source of an image or when you are looking for an exactly similar image but of a different dimension – see example.
Google has recently updated the Similar Images feature to include support for the site: operator as well. That means you now have an easy option to show only similar images that are available on a particular website or domain.
To get started, use the site: operator to find any specific picture on a site – like site:apple.com steve jobs. Then choose the “Similar Images” option with any of the images in the results to find all the other pictures on that site that are possibly similar.
