Google and Google Images are search engines not sources. They point you to information and images that exist on the internet. In order to cite the images you might find using Google Images, you must visit the page where Google found the original image. Click the "visit" button to the right of the image. If you cannot find enough information to cite the image, find a more credible image.
Simon Fraser University has a good example of how to incorporate images into your paper - you need to fully describe each image and refer to each figure by its number (Figure 1 for example).
Images
Basic Format for an Electronic Image
Author (Role of Author). (Year image was created). Title of work [Type of work], Retrieved from URL (address of website)
Note: If you can only find the screen name of an author (such as a photographer on Flickr), that will do as the author's name.
If the screen name is all lowercase, keep the name lowercase in the in-text citation and the references list.
Electronic Image (No Author)
Title of work [Type of work]. (Year image was created). Retrieved from URL (address of website)
Electronic Image (No Author, No Title, No Date)
Many images found on the Web are of this category, but you should still look for this missing information: try clicking on the image, and/or looking at the bottom of the image.
