This is not possible. If browser followed the current specifications, 
then what I did in 2008 could happen for sinister purposes, not just 
reverse testing of IE8. I was able track the visits from Redmond for

1px by 1px images.

You can track visited URLs very simply using hidden background images 
requested by using :visited.
