<img src="http://www.yourserver.com/image.php?ID=xxx";>

Do what you need to do with the PHP code as far as keeping a count of
visitors, etc, and then create an image header and send it the data for a
1x1 pixel transparant image.

Got a question for everyone else, b/c I'm not sure on this. If I have a link
like the above on www.example.com, say, and it linkes to
www.yourserver.com/image.php, can I start a session in that file and have it
carry over each time this image is called?  i.e. image.php would start a
session, see if one already exists, update counts and "track" of user, then
send image headers and data. Will that work? I'm at work now, so I can't
test it. What I'm worried about is the session cookies being accessible when
it's an image being requested, not a web page...

Any suggestions welcome...
