Click the image you wish to use. This will take you to the website from which the image came. Depending on your browser, you might then have an enlarged version of the image appear overlaid on the website. Click the blue "X" on the upper right corner of the image to access the website itself.
Review the website to see if it has any attribution for the image if you are uncertain of whether the website's maintainers created the image. For instance, if you find the image on a blog or social network page instead of a newspaper or academic site, the blogger may mention that he found the image somewhere else or provide a link to the original source of the image. This will prevent you from incorrectly attributing the source to the wrong author.
Contact the maintainer of the site to ask where she obtained the image if you are unsure of its reliability or if you know the author could not be the original source of the image. For instance, if someone has a professional-looking graph about public opinions on the Iraq War in her blog, it is unlikely that she created it because she would have had to conduct the poll herself. If you email her and find out where she obtained the graph, you can cite the graph's actual creator. This will make your paper more accurate and will also grant it more reliability, as your readers are more likely to trust information from a Gallup poll than from a stranger with a blog.
Cite the website in-text by writing the author's last name, any given date for the website and any relevant page numbers. If the site has no page number, do not provide one. If the site has no date, write "n.d." in place of the date. If the site has no author, write the title of the website in quotation marks. For instance, when citing an article with an author but no date, you would write (Greydanus, n.d.) When citing an article with no author or date, you would write ("Alcohol-Related Traffic Fatalities").
Cite the website in your bibliography by writing the author's last name, a comma and the author's first initial. If the article has an organization as its author, write the organization's name in place of the author's name. Write the date of publication in parentheses, or "n.d." if you don't know the date. Write the article title, if you are citing a website that uses articles, followed by the title of the host website. For both of these titles, capitalize only the first letter of the citation and any proper nouns. Conclude by writing "Retrieved from" followed by the URL. For instance, you would cite a source with a host website as follows:
Kingsley, E.P. (1987). Welcome to Holland. National Down Syndrome Society. Retrieved from http://www.ndss.org/index.php?option=com_content&view=article&id=206%3Aa-parents-perspective&catid=67%3Aa-parents-perspective-on-having-a-child-with-a-di&Itemid=133
You would cite a source without a host website, or where the host website's name is the same as the organization's name, as follows:
National Down Syndrome Society (2011). A promising future together. Retrieved from http://www.ndss.org/images/stories/NDSSresources/pdfs/new%20parent%20packet.pdf
Cite an online news article, magazine article or journal article exactly as you would its physical counterpart. At the end, write "Retrieved from" followed by the URL. For example:
Shea, M. P. (2011, June 28). Charisms don't make you a saint. Crisis Magazine. Retrieved from http://www.crisismagazine.com/2011/charisms-dont-make-you-a-saint
Cite a graph from a reputable academic source by naming the organization that conducted the study followed by the date. In brackets, give the title of the graph or a brief description of it. Afterwards, provide the project name and the URL. For example:
The Pew Forum on Religion & Public Life. [Graph of income distribution within U.S. religious groups Jan 30, 2009]. U.S. Religious Landscape Survey. Retrieved from http://www.pewforum.org/Income-Distribution-Within-US-Religious-Groups.aspx
