Google offers you a way to search through billions of graphics for school or personal use.
Go to www.google.com and click Images at the top right of the page.
Type your search term(s) into the search box.
You can include the word “graph,” “chart,” “statistics,” etc. if that is the type of visual aid you are looking for. For example, the keywords “gasoline prices” and graph will retrieve graphs relating to gas prices.
Click the blue magnifying glass to search.
Google will present a collection of graphics that match your search terms. For example, the above search retrieves the images below (click for a larger image):
You can filter your results to get different images. Click on Search tools, above your results, and a new menu will show up underneath.
Clicking on an image will bring up more information and a list of similar images. This screen includes a link which will take you to the original page where the image was found - including the information needed to correctly cite the image.
While using Google Image Search, did you happen to notice the little grey camera in the search box? If not, go back and look. This is a different kind of image search - it lets you search BY image instead of typing in search terms. This can be really helpful if you have a picture and need more information about it or need to identify a logo or emblem.
