In order to cite an image you will need some information, much like citing text. You will need the following:
At the very least, but still do your best:
Captions appear below the image and typically begin with the abbreviation for Figure (Fig.), then followed by assigned Arabic numerals and a brief description.
An entry in the works-cited list is not necessary if an image caption provides complete information about the source, and it is the only time the source is referenced in the text.
Remember to NEVER cite Google Image as the source of an image. You will want to find the original location of an image, by clicking on the image.
Use the drop down tabs to see how to cite images in each style. You can always consult the Purdue Owl Writing Lab Online Research & Citation Resources.
