"Many corporations have programs called "spiders" that will search out images
and text on Web pages. If it matches the criteria (same file name, content
matches, and other things), they will flag that site for review and it will
be reviewed for copyright infringement. These spiders are always surfing the
net, and new companies are using them all the time." Quote taken from the website: www.webdesign.about.com
