Quite simple. They serve a different image if the image is not being
included in *their* page. Look at *their* page you get the correct image.
Look directly at the image, or include the image on *your* page, you get
something else. This is to stop bandwidth stealing.
The image you get is only a gentle hint to use *their* page to look at the
image. There have been reports of people replacing images with something
that, shall we say, you would not display in mixed company.
