BTW, it deserves mentioning that all of the artwork on this site is ripped from Microsoft's online Office clip-art database.
A few years back I used to have a job where I had to access it regularly and I got to know it quite well.
I don't know if using this artwork on a site like this is technically legal with the license on MS' clipart, but in today's sue-happy world, I'd say it's risking the usual legal BS so many sites get into nowadays.
