Another great search feature by Google. When you search for an image and then want to find similar images, this feature is the perfect solution.
Here is a video that explains this search feature:
This is a great tool for teachers. Let's say you are teaching students about Spanish art and would like to show them works of Picasso. If you type in the word 'Picasso', the search will generate a whole collection of art work by Picasso and also photos of the artist.
This search can also be used if you are looking for photos of a city. Type 'Madrid' and you will find a collection of different photos of places around Madrid.
