You do not have to leave your Google Doc to search images. You are able to search within any Drive program for images from Google, LIFE magazine, and stock photos. The photos pulled up in this search are also images that can be reused with modifications, which means you have permission to use the images, a much better option to going to Google Images and just searching randomly!
This works within any Drive program: Docs, Presentation, Forms, etc.
Once you search, you can narrow your search to show just faces, photos, clip art, or line drawings. This is a really neat feature that can be useful for projects. I searched the butterfly life cycle and was able to look at photos, clip art, and line drawings - which showed a lot of diagrams.
I really like that these are images you can use freely without worrying about use.
