A: To cite an image found through Google using the image-search function, you must identify the Web site where the image was posted. Then, cite the image like you would if you found it through the original website where it was posted. If the image has no official title, create a short description of your own.
Example (MLA 8):
Title of image or your own description of the image. Digital Image. Title of the website where it was published (not google!). Date it was published (if you know it). URL.
