More and more web pages are making use of snap-shots (http://real.snap.com/). This is a "feature" that allows websites to have links that when you hover over them, a little window pops up showing some additional content, usually an image or video. If you find these types of links as annoying as I do, the good news is that the folks at snap-shot allow you to turn this off. You have to visit their FAQ here: http://real.snap.com/about/shots_faq.php#3 and click on a link on their page. This sets a cookie on your browser which disabled the snap-shot popup "feature".
