When searching Google Images, if you want to filter and customize the image search results you see, use the options along the side of the results page. For instance, you can choose just to see black and white photos or only images of a certain size (which is important to consider when doing a presentation). You can limit to clipart images or line drawings or photos.
How to Cite an Image
An Image (Including a Painting, Sculpture, or Photograph)
"If the work is cited on the web only, then provide the name of the artist, the title of the work, the medium of the work, and then follow the citation format for a website. If the work is posted via a username, use that username for the author."
An Article in a Web Magazine
"Provide the author name, article name in quotation marks, title of the Web magazine in italics, publisher name, publication date, medium of publication, and the date of access. Remember to use n.p. if no publisher name is available and n.d. if no publishing date is given."
