Image Dictionary is a Chrome extension that enables users to right-click on a word and quickly find an image that is representative of that word. To use the Image Dictionary extension just highlight a word on a webpage, right-click, and select "image search." The images that are shown come from Wikipedia.

Image Dictionary could be a handy little extension to use when you want to quickly find an image to represent a plant, animal, or perhaps a broad topic. I'm thinking that it would be helpful at those times when a student is reading an article and comes across a word that they understand, but don't have a visual connection to. For example, if I'm reading about sloths I know that they're animals, but I don't have a good visual picture of them. Using the Image Dictionary extension quickly brings up a picture for me so that I can get on with my reading.
