Just to ask knowledgable ppl

Not directly PHP related, but I'm building a site in PHP at the moment, so I've been doing a bit of research... I've been on the net for years, coding and surfing and coding. And not always in that order. ;) But only recently have I heard about web beacons, or single-pixel gifs. Seems every site with these beacons mentions them in their privacy policy. Shows you how much I pay to attention to them. I was just curious as to how they work. Is it just a matter of viewing server reports to see how often that image has been accessed? _________________________________________________________________ Add photos to your e-mail with MSN 8.
