Web bugs are images hidden in web pages, typically they are only 1 x 1 pixel in size and are used for tracking and statistics.
Here's a quote from The Privacy Foundation's (http://www.privacyfoundation.org/resources/webbug.asp#1) FAQ page....

What exactly is a Web Bug?

A Web bug is a graphic on a Web page or in an Email message that is designed to monitor who is reading the Web page or Email message. Web bugs are often invisible because they are typically only 1-by-1 pixel in size. They are represented as HTML IMG tags. For example, here are two Web bugs recently found on Quicken's home page (www.quicken.com):


<img src="http://ad.doubleclick.
net/ad/pixel.quicken/NEW"
width=1 height=1 border=0><IMG WIDTH=1
HEIGHT=1border=0SRC=

ny&db_afcr=4B31-C2FB-10E2C&event=
reghome&group=register&time=
1999.10.27.20.5 6.37">
The two Web bugs were placed on the home page by Quicken to provide "hit" information about visitors to DoubleClick and MatchLogic (AKA, preferences.com), two Internet advertising companies.

Sneaky huh?
