You should provide sources for images that you use in a paper, presentation, or other venue, just as you would cite authors of works that you have quoted. This means providing specific information about the site where you found the image.
If you find an image using a Google Images search, remember that Google isn't the original source of the image -- it is the site that did the searching. In your citations, provide the specific address of the website on which the image was located, not the Google results page.
In-Text Citations and Captions
Check with your instructor to see if they have specific preferences for your in-text citations. Generally, you should label each image with "Figure" or "Fig." followed by a number, and then provide as much of the following information as possible. When you discuss the image in the text of your paper, write "(see Fig. 1)" when you refer to the work.
For all images:
Artist’s name [first name then last], title [italicized], date. Medium and support, measurements.
Example: Guido Reni, Joseph and Potiphar's Wife, c. 1630. Oil on canvas, 128.9 x 170 cm.
For an image of a museum object:
Artist’s name [first name then last], title [italicized], date. Medium and support, measurements, repository, and city.
