Citing online images

How does one cite an online image? I had no idea (it’s been a while since I’ve written anything academic), so I searched online. A Google search for “bibliography reference for internet image” led me to a useful page at a virtual middle school library site (how appropriate).

To quote from that page:

Photographer's or artist's name (often not given)
Name of subject or title of picture
Date of picture (often not given)
Title of website
URL
Date you accessed the picture

So, for example, my table on divorce rates in Malaysia, which seems to be quite popular, would be cited as:
Yahya, Meor Azmal. Average Divorce Rate (2000-2005). 18 Nov 2009. on Everything, on nothing. http://lothaq.blogspot.com/2009/11/divorce-statistics-in-malaysia.html 22 May 2010.

What happens if there’s more than one image at that URL? Hmm. Needs work. Hehe.

Btw, citing the site I went to should be done like so:
Bibliography Format. Virtual Middle School Library, The American School in Japan. 12 May 2010. 22 May 2010. <http://www.asij.ac.jp/middle/lib/BibliographyFormat/Bibliography%20Format.htm>
