Its Tracking Me

OK so I am making a web site for a biotech company and they require a web traffic tracking method for the site. I can't seem to find a service that doesnt require some sort of image to be placed on the site. So, would anyone know of any web site tracking program, preferably free that doesn't require an image placed on the site. I little Javascript or something placed in the code would be ok. I just dont want something that messes with my design.

By the way, thank you all who bothered to look at this thread.

There are plenty of server-based web stats applicaitons. They parse the log files and compile the various statistics. Is this what you're looking for?

no i am looking for something basic that says total visits, average amount of visits per day, etc.

Google: awstats,
webalizer,
or CGI scripts that can do that for you.

Thank you, i'll try those.
